Procedure

cis-3-Methoxycarbonyl-5-[N-(1-(4-cyanobenzyl)-1H-imidazol-5-ylethyl)carbamoyl]piperidine (59.0 mg, 0.149 mmol) was dissolved in MeOH (2 mL). Phenylacetaldehyde (52.3 ul, 0.447 mmol) was added followed by sodium cyanoborohydride (28.1 mg, 0.447 mmol). The solution was stirred overnight at ambient temperature. The MeOH was removed under reduced pressure and chromatography (silica gel, 1-2% MeOH/CH2Cl2 /NH4OH) gave the title compound as a white solid. 1H NMR (CDCl3); δ 7.62 (d, 2H, J=8 Hz), 7.50 (s, 1H), 7.08-7.37 (m, 7H), 6.88 (s, 1H), 6.46 (br s, 1H), 5.22 (s, 2H), 3.64 (s, 3H), 3.27-3.19 (m, 1H), 3.03-3.20 (m, 1H), 2.86-3.00 (m, 1H),2.73-2.85 (m, 3H), 2.44-2.70 (m, 5H), 2.26-2.41 (m, 2H), 1.98-2.10 (m, 2H), 1.80-1.95 (m, 1H).
