Reaction Steps

To 5-chloro-7-morpholinothiazolo[4,5-d]pyrimidine-2-carbaldehyde 43 in 50 mL Toluene and 50 mL THF was added 30 mL of NH2Me (40% in water) and the mixture stirred under N2 for two days. The mixture was concentrated in vacuo and redissolved in 50 mL THF and 50 mL MeOH followed by the portionwise addition of 1.6 g (4.0 eq) NaBH4 and the reaction mixture stirred overnight at room temperature. Complete reaction was confirmed by LCMS and the mixture was concentrated in vacuo and purified by flash chromatography (95/5% EtOAc/EtOH 20 min followed by a gradient up to 100% EtOH over 30 min more) to give 1-(5-chloro-7-morpholinothiazolo[4,5-d]pyrimidin-2-yl)-N-methylmethanamine 60.
