Reaction Steps

A mixture of 4-(2-aminopyrimidin-5-yl)-2-fluoro-N-methylbenzamide (123 mg, 0.5 mmol) and chloroacetaldehyde (0.318 mL, 2.5 mmol) in isopropyl alcohol (4 mL) was stirred at 90° C. for 4 h. The solvent was removed under vacuum and the residue was triturated with ethyl acetate and hexanes. The solid formed was collected and dried under reduced pressure to give the desired product (120 mg, 88.8%). LCMS: (M+H)=271.0.
