PROCEDURE
实验过程
A sealed tube was charged with {4-[3-(6-bromo-pyridin-2-yl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester (from Example 33 supra) (500 mg, 0.809 mmol), thiophen-3-yl-methylamine (118 mg, 1.044 mmol), Pd2(dba)3 (47 mg, 0.0817 mmol), DavePhos (64 mg, 0.163 mmol), t-BuONa (109 mg, 1.135 mmol) and dioxane (20 mL). The mixture was stirred at 102° C. under an atmosphere of N2 for 12 hours. After cooling to room temperature, the mixture was filtered and concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, 12 g, 200-300 mesh, eluting with petroleum ether:ethyl acetate, 3:1) to give {4-[3-{6-[(thiophen-3-ylmethyl)-amino]-pyridin-2-yl}-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester. (Yield 415 mg, 79%).
