Reaction Conditions

Reaction Steps

A mixture of 3-[(adamantan-1-ylmethyl)carbamoyl]-1-[2-(3-cyanophenyl)-2-oxoethyl]-2-methylpyridinium bromide (400 mg, 0.81 mmol) and N,N-dimethylformamide dimethyl acetal (0.22 mL, 1.62 mmol) in DMF (2.0 mL) is stirred at 110° C. for 3 h. The mixture is concentrated in vacuo and purified by column chromatography (gradient from CH2Cl2 to 10% EtOAc/CH2Cl2) to give the title compound as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ 9.91 (1H, d), 8.53 (1H, t), 8.15 (1H, m), 8.05 (2H, m), 7.74 (1H, t), 7.66 (1H, dd), 7.44 (1H, d), 7.22 (1H, t), 6.95 (1H, d), 3.01 (2H, d), 1.93 (3H, s), 1.63 (6H, m), 1.52 (6H, s). Mass spec. (438.19, M+H).
