Participants

Reaction Steps

To a solution of acetyl chloride (114 mL, 1.6 mol) in 290 mL of MeOH at 0° C. was added a solution of (S)-tert-butyl (1-(imidazo[1,2-a]pyrazin-8-yl)pyrrolidin-3-yl)carbamate (111.7 g, 0.37 mol) in 450 mL of MeOH. The reaction mixture was stirred at room temperature for 2 h then heated at 60° C. for 30 min. The product was filtered, washed with 200 mL of MeOH and dried in a vacuum oven to afforded (S)-1-(imidazo[1,2-a]pyrazin-8-yl)pyrrolidin-3-amine (101.2 g, 1.6 mol, 100%).
