PROCEDURE
实验过程
A mixture of (S)-methyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-chloropyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate (0.055 g, 0.107 mmol), 1,3-dimethyl-5-(tributylstannyl)-1H-pyrazolo[4,3-d]pyrimidine (0.058 mg, 0.133 mmol), copper(I) iodide (6 mg, 0.032 mmol) and tetrakis(triphenylphosphine)palladium(0) (11 mg, 0.012 mmol) in dioxane was heated at 90° C. for 16 hr. Reaction mixture was cooled to rt, filtered through a syringe filter and purified by CombiFlash (12 g, Gold, 10-100% EtOAc/Hex, then 15% MeOH/CH2Cl2 to elute product) to give impure product that was used in next step without further purification. LCMS-ESI+: calc'd for C33H32ClN6O3S: 627.2 (M+H+); Found: 627.2 (M+H+).
