To a mixture of methyl 4-(1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)pyrrolidin-3-ylcarbamoyl)-2-hydroxybenzoate (100 mg, 0.18 mmol) in 2 mL of DMF were added MeI (38 mg, 0.27 mmol) and K2CO3 (37 mg, 0.27 mmol) at room temperature, and then the mixture was stirred for 16 hours. The mixture was poured into water and extracted with EtOAc (3×5 mL). The organic layer was washed with 0.1 N HCl (5 mL) and brine. The organic layer was dried over Na2SO4. After filtration and concentration, the crude methyl 4-(1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)pyrrolidin-3-ylcarbamoyl)-2-methoxybenzoate was obtained and used the next step without purification (80 mg, 78%). LC-MS: 565 [M+H]+, tR=1.48 min.
