Reaction Steps

Zn (2.66 g, 40.7 mmol) was added in 2 portions over a period of 2 minutes to a mixture of (1-methyl-1H-imidazol-5-yl)(3-methyl-4-nitrophenyl)methanone (2.0 g, 8.1 mmol, Intermediate 14: step b) and NH4Cl (2.18 g, 40.7 mmol) in acetone (18.5 mL) and water (8.2 mL) at 0° C. After stirring for 1 hour, the reaction mixture was filtered through Celite®, rinsing with EtOAc. Acetone and EtOAc were removed on a rotary evaporator and the aqueous layer was filtered and the solids dried under vacuum to provide the title compound.
