Reaction Steps

To a solution of 3-(5-amino-4-cyano-imidazol-1-yl)-N-cyclopropyl-4-methyl-benzamide 3 (56.4 mg, 0.2 mmol) in dry THF (10 ml) under nitrogen was added phenylmagnesium bromide (1M, 1 mL) at room temperature. After 1 h, HCl solution (3N, 10 ml) was added and the mixture was stirred overnight. The solution was neutralized with dilute aqueous NaOH. The mixture was extracted with ethyl acetate (100 mL×2), washed with water and dried over Na2SO4. Evaporation of the solvent gave a residue which was purified by HPLC to give 3-(5-Amino-4-benzoyl-imidazol-1-yl)-N-cyclopropyl-4-methyl-benzamide as a while solid (56 mg, 78%). LCMS (4 minute gradient) tR=2.07 min; MS m/z 361.17 [M+H]
