The reaction was stirred for 1 hour at −78° C. upon which 3 eq of acetone were added. The reaction was subsequently warmed to 0° C. after 30 minutes. The reaction was quenched with water and extracted with ethyl acetate. The organic layer was concentrated to give crude 2-(2-chloro-9-methyl-6-morpholino-9H-purin-8-yl)propan-2-ol (95 mg).
