The mixture of (S)-5-chloro-N-(3-methoxy-5-(2-methylpyrrolidin-1-yl)phenyl)thiazolo[5,4-d]pyrimidin-7-amine (200 mg, 0.53 mmol), methyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (153 mg, 0.585 mmol), Pd2(dba)3 (61 mg, 0.11 mmol), X-Phos (102 mg, 0.21 mmol) and Na2CO3 (169 mg, 1.6 mmol) in dioxane (20 mL) and water (5 mL) was heated to 100° C. with stirring for 16 h under N2. The solvent was removed in vacuo and the resulting residue was purified by column chromatography (petroleum ether:ethyl acetate=20:1) to afford (S)-methyl 4-(7-(3-methoxy-5-(2-methylpyrrolidin-1-yl)phenylamino)thiazolo[5,4-d]pyrimidin-5-yl)benzoate (121 mg, 48%) as yellow oil. LC-MS: 476 [M+H]+, tR=1.999 min.
