Reaction Steps
A mixture of 5,7-dichlorothiazolo[5,4-d]pyrimidine (0.925 g, 4.49 mmol), 3,4-dimethoxybenzenamine (0.89 g, 5.8 mmol) and DIEA (0.86 g, 6.66 mmol) in 12 mL of DMSO was stirred at room temperature for 24 hours. Then the reaction mixture was poured into 50 mL of water, the solid was filtered and washed with water (50 mL) to give a crude product as a solid. It was purified by silica gel chromatography (silica gel 200-300 mesh, eluting with ethyl acetate) to give 5-chloro-N-(3,4-dimethoxyphenyl)thiazolo[5,4-d]pyrimidin-7-amine (1.2 g, 82.8%) as a grey solid. LC-MS: 322.9 [M+H]+, tR=1.51 min.
