An improved and efficient method for the synthesis of panobinostat was developed. The commercially available starting material 4-(chloromethyl)benzaldehyde was converted to (E)-methyl 3-[4-(chloromethyl)phenyl]acrylate via the Wittig-Horner reaction and was then directly condensed with 2-(2-methyl-1H-indol-3-yl)ethanamine to afford the key intermediate (E)-methyl 3-[4-({[2-(2-methyl-1H-indol- 3-yl)ethyl]amino}methyl)phenyl]acrylate in a one-pot synthesis reactor. Subsequently a nucleophilic substitution reaction was carried out smoothly to generate the desired compound. The key intermediate and target compound were characterised by HRMS, 1H NMR and 13C NMR. This procedure is operationally simple and would be more suitable for industrial production.

(Chemical Equation Presented) We have prepared immobilized olefins as models for the cross metathesis using different olefin partners in the presence of second generation Grubbs and Hoveyda-Grubbs precatalysts. We have demonstrated that solid-phase cross metathesis is strongly dependent on the degree of homodimerization of the non-immobilized olefin and the reactivity of such a homodimer. As in the homogeneous phase, the Hoveyda-Grubbs precatalyst was better for immobilized α,β-unsaturated carbonyl compounds.

A compound having the following formula (I): wherein R?1? is N-containing heterocyclic ring optionally substituted with one or more suitable substituent(s), R?2? is hydroxyamino, R?3? is hydrogen or a suitable substituent, L?1? is -(CH?2#191)?n#191- (wherein n is an integer of 0 to 6) optionally substituted with one or more suitable substituent(s), wherein one or more methylene(s) may be replaced with suitable heteroatom(s), and L?2? is lower alkenylene, or a salt thereof. The compound is useful as a histone deacetylase inhibitor.
