A mixture of 5,7-dichlorothiazolo[5,4-d]pyrimidine (170 mg, 0.83 mmol), 3-(2-(methoxymethyl)pyrrolidin-1-yl)aniline (170 mg, 0.83 mmol) and DIEA (214 g, 1.66 mmol) in 15 mL of DMSO was stirred at room temperature overnight. 100 mL of water were added, the mixture was extracted with ethyl acetate (3×30 mL). The organic layer was washed with water (2×30 mL) and brine (30 mL), concentrated under reduced pressure to give 5-chloro-N-(3-(2-(methoxymethyl)pyrrolidin-1-yl)phenyl)thiazolo[5,4-d]pyrimidin-7-amine (200 mg, 64%) as a yellow solid. LC-MS: 376 [M+H]+, tR=1.75 min.
