Reaction Steps

To a microwave vial containing a solution of N-methylpyrimidin-2-amine (90b, 290 mg, 2.7 mmol) in acetonitrile (5 mL) was added 2-bromo-1-phenylethanone (714 mg, 3.6 mmol). The vial was sealed and heated in a microwave reactor at 130° C. for 20 minutes and then cooled to room temperature. The reaction mixture was treated with hydrazine hydrate (0.65 mL, 13.3 mmol) and then heated in a microwave reactor at 100° C. for 5.0 minutes. The solution was poured into water and filtered the precipitate to give 1-methyl-5-phenyl-1H-imidazol-2-ylamine (90c).
