Also, to a solution of 5-chloro-7-morpholinothiazolo[5,4-d]pyrimidine-2-carbaldehyde 44 in 50 mL THF was added 20 mL of 40% methylamine in water. The reaction mixture was stirred at room temperature under N2 for 24 hours. The solvents were removed in vacuo and the residue was dissolved in 50 mL MeOH and 50 mL THF and the NaBH4 added portion-wise. This reaction mixture was stirred at room temperature under N2 for 24 hours and complete reaction was confirmed by LCMS. The solvents were removed in vacuo and the crude product purified by flash chromatography (EtOAc/EtOH) to give of 1-(5-chloro-7-morpholinothiazolo[5,4-d]pyrimidin-2-yl)-N-methylmethanamine 61.
