実験手順

DIPEA (171 mg, 1.32 mmol) was added to a stirred solution of 1-o-tolyl-1H-[1,2,3]triazole-4-carboxylic acid (60 mg, 0.29 mmol) (prepared by the method used for the synthesis of Intermediate 64, starting from 2-methylaniline) in DMF (5 mL) followed by HOBt (44 mg, 0.32 mmol) and EDCI (141 mg, 0.73 mmol). After 2 minutes of stirring, 2-amino-1-[4-(3-trifluoromethyl-phenoxy)-piperidin-1-yl]-ethanone hydrochloride (prepared according to Step 1 and 5 of the General Scheme) (110 mg, 0.32 mmol) was added and the resulting mixture was stirred at ambient temperature overnight. Cold water was then added and the solid was collected. The solid obtained was purified by recrystallisation from a solvent system (3:7:0.2), EtOAc:hexane:MeOH to afford 124 mg (86.17% Yield) 1-o-tolyl-1H-[1,2,3]triazole-4-carboxylic acid {2-oxo-2-[4-(3-trifluoromethyl-phenoxy)-piperidin-1-yl]-ethyl}-amide. LC/MS [M+H]+: 488, 98.68%. 1H NMR (300 MHz, DMSO-d6): δ 9.0 (s, 1H), 8.5 (t, 1H), 7.6-7.48 (m, 4H), 7.48 (m, 1H), 7.36 (t, 3H), 4.9 (m, 1H), 4.3 (d, 2H), 4.0 (s, 1H), 3.8 (s, 1H), 3.6 (m, 2H), 2.2 (s, 3H), 2.1 (t, 2H), 1.7 (s, 1H), 1.6 (s, 1H).
