Reaction Steps

A solution of 3-aminopropanenitrile fumarate (147 mg, 0.74 mmol) and sodium methoxide (1.1 mL, 0.54 mmol) in MeOH (2 mL) was added dropwise to an ice-cold solution of 2,4-dichloro-6-((2,2,2-trifluoroethoxy)methyl)pyrimidine (64 mg, 0.25 mmol) in acetonitrile (2 mL). The mixture stirred at rt over night. The mixture was heated to 50° C. for 20 h. The reaction mixture was concentrated in vacuo and the crude was partitioned between EtOAc and 1M NaOH. The organic layer was concentrated in vacuo and the residue was purified by preparative HPLC to give the title compound, 29 mg (40%).
