c-Met and VEGFR-2 have attracted interest as novel targets for treatment of various cancers. Aiming to develop potent dual c-Met and VEGFR-2 inhibitors, a series of pyrrolo[1,2-f][1,2,4]triazine derivatives were designed and synthesized. The majority of target compounds exhibited potent antiproliferative effect against c-Met addictive cancer cell lines with IC50 values ranged from 1.2 to 24.6 nM, especially 27a. In-depth studies demonstrated 27a has great selectivity to c-Met and VEGFR-2, and potent inhibitory activity against them (IC50 of 2.3 ± 0.1 nM and 5.0 ± 0.5 nM). Furthermore, it also showed the highest anticancer activity with IC50 of 0.71 ± 0.16 nM (better than the positive compound) against BaF3-TPR-Met and 37.4 ± 0.311 nM (comparable to the positive compound) against HUVEC-VEGFR2, consistent with that in c-Met sensitive tumor cell lines. Subsequently, physicochemical and pharmacokinetic characterization indicated 27a has favorable druggability and pharmacokinetic properties. Further docking studies suggested a common mode of interaction at the ATP-binding site of c-Met and VEGFR-2, also indicating that 27a was a potential candidate for cancer therapy deserving further study.

Functionalized pyrrolotriazine 1b is a key heterocyclic building block in the synthesis of BMS-690514, a potent anticancer agent. Described herein are our development activities that led to the efficient preparation of 1b on a large scale. The key transformations include a selective C-alkylation of an oxalacetate salt with a hydrazonyl bromide to form a 2-hydrazonoethyl-3- oxosuccinate, followed by cyclodehydration to an aminopyrrole. Subsequent deprotection and condensation with formamidine afforded the pyrrolotriazine scaffold. Further elaboration of this core provided the desired pyrrolotriazinyl amine.

The development of a practical synthesis for a p38 kinase inhibitor is described. The key advances include an improved route to the key intermediate, a substituted pyrrole, and a subsequent animation utilizing O-(4-nitrobenzoyl)- hydroxylamine, which provides a safe, scalable, and robust amination method. The new protocol was successfully demonstrated to generate 1.6 kg of API in seven steps and 26% overall yield.

Processes are provided for selectively preparing novel stable crystalline salt forms, selectively and consistently, namely, preparing Form N-1 of the methanesulfonic acid salt, and Form N-1 and Form N-4 of the hydrochloric acid salt of the p38 kinase inhibitor 4-[[5-[(cyclopropylamino)carbonyl]-2-methylphenyl]amino]-5-methyl-N-propylpyrrolo[2,1-f][1,2,4]triazine-6-carboxamide. The processes preferably employ solvent systems including formic acid/acetone and formic acid/methylethyl ketone which produce crystals having suitable flow properties and desired particle size, and solvents such as N,N-dimethylformamide and N,N-dimethylacetamide may be employed as well. Novel Form N-1 crystals of the Form N-1 and Form N-4 crystals of the hydrochloride salt and Form N-1 crystals of the methanesulfonic acid salt of the above free base, pharmaceutical compositions containing such novel forms and a method of treating p38 kinase associated conditions, including rheumatoid arthritis are also provided.
