Procedure

A solution of 1-phenyl-4,5,6,7-tetrahydro-1H-[1,2,3]triazolo[4,5-c]pyridine (17 mg, 0.085 mmol) and 2,3-dichlorobenzoic acid (18 mg, 0.093 mmol) in DCM (8 ml) was treated with Et3N (35 μL, 0.25 mmol) followed by HATU (38 mg, 0.1 mmol). The reaction was stirred overnight, then concentrated to minimum volume and purified on 16 g SiO2 with 0-3.5% NH3 in MeOH/CH2Cl2 to give 24 mg (75%) of 5-[(2,3-dichlorophenyl)carbonyl]-1-phenyl-4,5,6,7-tetrahydro-1H-[1,2,3]triazolo[4,5-c]pyridine. MS (ESI): mass calcd. for C18H14Cl2N4O, 372.0; m/z found, 373.2 [M+H]+. 1H NMR (400 MHz, CDCl3) δ 7.63-7.42 (m, 5H), 7.38-7.17 (m, 2H), 5.23-4.88 (m, 1H), 4.54 (q, J=15.7 Hz, 1H), 4.23 (dt, J=13.2, 5.5 Hz, 1.0H), 4.10-4.00 (m, 1.0H), 3.65-3.48 (m, 1H), 3.03 (t, J=5.7 Hz, 1H), 3.00-2.74 (m, 1H).
