, (2022/03/27)
The invention relates to the field of synthesis of organic matters, and particularly discloses a synthesis method of a six-membered ring benzylamine compound, which comprises the following steps: taking a compound D, a compound E and potassium tert-butoxide as raw materials, taking dimethyl sulfoxide as a solvent, reacting at 5-10 DEG C for 1-2 hours, heating to 20 DEG C, reacting, and purifying and separating after the reaction is finished to obtain a compound A; the method comprises the following steps: by taking a compound A, potassium carbonate and hydrogen peroxide as raw materials and dimethyl sulfoxide as a solvent, reacting at 50-65 DEG C, adding ice water to separate out a product after the reaction is finished, filtering and washing to obtain a compound B; dissolving the compound B in acetonitrile, adjusting the pH value to 13-14, adding a saturated sodium hypochlorite solution for reaction, and purifying and washing after the reaction is finished to obtain a compound C; the method has the effect of improving the defect that the synthesis process of the six-membered ring benzylamine compound is not suitable for industrial production.
(3R)-3-Amino-4-(2,4,5-trifluorophenyl)-N-{4-[6-(2-methoxyethoxy)benzothiazol-2-yl]tetrahydropyran-4-yl}butanamide as a potent dipeptidyl peptidase IV inhibitor for the treatment of type 2 diabetes

Novel series of 3-amino-N-(4-aryl-1,1-dioxothian-4-yl)butanamides and 3-amino-N-(4-aryltetrahydropyran-4-yl)butanamides were synthesized and evaluated as dipeptidyl peptidase IV (DPP-IV) inhibitors. Derivatives incorporating the 6-substituted benzothiazole group showed highly potent DPP-IV inhibitory activity. Oral administration of (3R)-3-amino-4-(2,4,5-trifluorophenyl)-N-{4-[6-(2-methoxyethoxy)benzothiazol-2-yl]tetrahydropyran-4-yl}butanamide (12u) reduced blood glucose excursion in an oral glucose tolerance test.

The mixed anhydride of 5-(aminosulfonyl)-2-methoxybenzoic acid (VII) and monoethyl carbonate reacted with benzylamine, 1-methylpiperazine, and 1-benzylpiperazine to give the 5-(aminosulfonyl)-2-methoxybenzamides II, IV, and V.Heating the ethyl ester X with 4-amino-1-methylpiperidine resulted in the amide III.Reaction of 5-(chlorosulfonyl)-2-methoxybenzoyl chloride (XI) with 1-benzylpiperazine afforded 5-(4-benzylpiperazinosulfonyl)-2-methoxybenzoic acid 4-benzylpiperazide (VI).Compounds II-VI are analogues of the antidopaminergic and antiemetic agent sulpiride (I) but only the benzylpiperazides V and VI showed indications of psychotropic activity of the neuroleptic type.
