実験手順

Tert-butyl 4-[5-(4-carbamoyl-3-fluorophenyl)benzo[d]oxazol-2-yl]piperidine-1-carboxylate (140 mg, 0.32 mmol) dissolved in DCM (25 ml) and added trifluoroacetic acid (1 ml). This mixture stirred at rt for 3 h. After completion of the reaction, DCM removed on rotavapour and residue was co-distilled with ether to obtain 2-fluoro-4-(2-(piperidin-4-yl)-benzo[d]oxazol-5-yl)-benzamide 2,2,2-trifluoroacetate (140 mg). 2-Fluoro-4-(2-(piperidin-4-yl)-benzo[d]oxazol-5-yl)-benzamide 2,2,2-trifluoroacetate (140 mg, 0.31 mmol) was dissolved in DMF (5 ml) and added isovaleric acid (34.6 mg, 0.34 mmol), EDC.HCl (147 mg, 0.77 mmol), HOBt (50 mg, 0.37 mmol) and TEA (0.4 ml, 2.47 mmol). After completion of the reaction, water added to the reaction mixture to obtain solid. Solid was filtered and washed with ether to obtain the titled compound (20 mg) as a brown solid. M.P.: 186-190° C. MS (m/z): 424.1 [M+H]+.
