実験手順

Under N2 atmosphere, 5-chloro-N-(3-(methylsulfonyl)phenyl)thiazolo[5,4-d]pyrimidin-7-amine (200 mg, 0.59 mmol), methyl 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (183 mg, 0.7 mmol), Pd(PPh3)4 (30 mg, 0.026 mmol) and Na2CO3 (127 mg, 1.2 mmol) in 5 mL of water was added into the mixture solvent of 5 mL of water and 50 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-(methylsulfonyl)phenylamino)thiazolo[5,4-d]pyrimidin-5-yl)benzoate (150 mg, 58%) as a yellow sold. 1H NMR (300 MHz, DMSO): δ 10.76 (s, 1H), 9.45 (s, 1H), 8.99-8.98 (m, 1H), 8.93 (s, 1H), 8.73 (d, 1H, J=7.8 Hz), 8.21-8.18 (m, 1H), 8.09 (d, 1H, J=7.8 Hz), 7.69-7.65 (m, 3H), 3.91 (s, 3H), 3.26 (s, 3H). LC-MS: 441 [M+H]+, 903 [2M+Na]+, 439 [M−H]−, tR=1.61 min. HPLC: 98.78% at 214 nm, 97.72% at 254 nm, tR=8.14 min.
