Reaction Steps

To a microwave vessel containing 2-amino-4-(3-bromophenyl)-4-(4-(difluoromethoxy)phenyl)-1-methyl-1H-imidazol-5(4H)-one (103 mg, 0.25 mmol) and cyclopropylboronic acid pinacol ester (84 mg, 0.5 mmol) in 4 ml of 1:1:3 ratio of EtOH:water:1,2-dimethoxyethane, palladium(0) teterakis and aqueous sodium carbonate (400 μL of 2N solution) were added. The reaction mixture was heated in CEM microwave at 165° C. (40 mW power) for 8 minutes. The reaction mixture was filtered, and partitioned between DCM and water. The water layer was extracted w/DCM and the combined organic layer was dried (MgSO4) and concentrated under reduced pressure to afford crude product which was purified by reverse chromatography ((M+H)+ 372.4).
