Procedure

Under N2 atmosphere, 5-chloro-N-(3-(2-(methoxymethyl)pyrrolidin-1-yl)phenyl)thiazolo[5,4-d]pyrimidin-7-amine (200 mg, 0.53 mmol), methyl 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (153 mg, 0.58 mmol), Pd(PPh3)4 (40 mg, 0.035 mmol) and Na2CO3 (112 mg, 1.06 mmol) in 5 mL of water was added in 30 mL of 1,4-dioxane. The mixture was stirred at reflux for 18 hours. The solvent was removed under reduce pressure and the residue was purified by silica gel chromatography, eluting with petroleum ether and ethyl acetate (3:1) to give methyl 3-(7-(3-(2-(methoxymethyl)pyrrolidin-1-yl)phenylamino)thiazolo[5,4-d]pyrimidin-5-yl)benzoate (150 mg, 59%) as a yellow sold. 1H NMR (300 MHz, CDCl3): δ 9.13 (s, 1H), 8.82 (s, 1H), 8.68 (d, 1H, J=7.8 Hz), 8.14 (d, 1H, J=7.8 Hz), 8.06 (s, 1H), 7.54 (t, 1H, J=7.8 Hz), 7.35 (s, 1H), 7.28 (t, 1H, J=7.2 Hz), 7.16 (d, 1H, J=7.8 Hz), 6.49 (d, 1H, J=7.5 Hz), 3.96 (brs, 4H), 3.57-3.50 (brs, 2H), 3.32 (s, 3H), 3.25-3.19 (m, 2H), 2.11-2.02 (m, 5H). LC-MS: 476 [M+H]+, tR=1.93 min. HPLC: 98.15% at 214 nm, 97.85% at 254 nm, tR=5.24 min.
