Procedure

A flask was charged with methanesulfonyl-acetic acid (14 mg, 0.10 mmol), EDCI (30 mg, 0.15 mmol), HOBt (14 mg, 0.10 mmol), DIEA (36 μL, 0.20 mmol) and 0.5 mL DCM and stirred at 25° C. After 10 min, a solution containing 4-cyano-1H-imidazole-2-carboxylic acid (2-cyclohex-1-enyl-4-piperidin-4-yl-phenyl)-amide TFA salt (40 mg, 0.08 mmol) (as prepared in Example 20, step (b)) and NEt3 (14 μL, 0.09 mmol) in 0.5 mL DCM was added and the reaction allowed to proceed for 10 h at 25° C. The reaction mixture was loaded on a 5-g SPE cartridge (silica) and the title compound was eluted with 10% EtOH/EtOAc to give 10 mg (25%) of a white solid. 1H-NMR (400 MHz, CDCl3): δ 11.60 (br s, 1H), 9.52 (s, 1H), 8.30 (d, 1H), 7.74 (s, 1H), 7.60 (dd, 1H), 7.03 (d, 1H), 5.86 (m, 1H), 4.84 (m, 1H), 4.18 (s, 2H), 4.12 (m, 1H), 3.32 (m, 1H), 3.20 (s, 3H), 2.82 (m, 2H), 2.30 (m, 4H), 1.98 (m, 2H), 1.84 (m, 5H), 1.72 (m, 1H). Mass spectrum (ESI, m/z): Calcd. for C25H29N5O4S, 496.2 (M+H). found 496.2.
