Reaction Steps

To a solution of 8-methyl-3-(tetrahydro-2H-pyran-4-yl)imidazo[1,5-a]pyrazine (0.888 mmol, 193 mg) in dichloromethane (10 mL) was added N-bromosuccinimide (0.888 mmol, 158 mg) and the reaction mixture was heated at 50° C. (bath temperature) for 15 min. Dichloromethane and water were added, the organic layer separated, washed with an aqueous sodium hydrogencarbonate solution, dried (sodium sulfate) and concentrated in vacuo to afford 246 mg of 1-bromo-8-methyl-3-(tetrahydro-2H-pyran-4-yl)imidazo[1,5-a]pyrazine.
