Procedure

The amide is synthesized according to example 1 by mixing (6,7-difluoro-1H-benzimidazol-1-yl)acetic acid (96 mg, 0.45 mmol) prepared according to scheme 2, 4-[4-(1-aminoethyl)-3-methylphenyl]tetrahydro-2H-thiopyran-4-carbonitrile (129 mg, 0.50 mmol) prepared according to scheme 14, Et3N (0.69 μL, 0.50 mmol) and HATU (189 mg, 0.50 mmol) in MECN (3.0 mL). The compound is purified by silica gel column chromatography (10% MeOH in DCM) (121 mg, 59%). 1H NMR (400 MHz, DMSO-D6) δ ppm 1.35 (d, J=7.03 Hz, 3H), 2.05-2.16 (m, 2H), 2.26-2.35 (m, 5H), 2.72-2.81 (m, J=14.06 Hz, 2H), 2.88-2.99 (m, J=12.50, 12.50 Hz, 2H), 5.01-5.11 (m, 3H), 7.16-7.26 (m, 1H), 7.30 (s, 1H), 7.33-7.38 (m, 1H), 7.39-7.48 (m, 2 H), 8.18 (s, 1H), 8.84 (d, J=7.42 Hz, 1H). MS [M+H], calcd: 455.5. found: 455.3.
