PROCEDURE

实验过程

5-Bromo-3-[2(R)-tert-butoxycarbonylamino-2-cyclohexylethyl]-1-[2,6-difluorobenzyl]-6-methyl-pyrimidine-2,4(1H,3H)-dione 4b (1.0 g, 1.79 mmol) in benzene/EtOH/ethylene glycol dimethyl ether (20/2/22 mL) was added 2-fluoro-3-methoxyphenylboronic acid (382 mg, 2.24 mmol) and saturated Ba(OH)2/water (˜0.5 M, 15 mL). The reaction mixture was deoxygenated with N2 for 10 minutes, tetrakis(triphenylphosphine) palladium (0) (208 mg, 0.18 mmol) was added and the reaction mixture was heated at 80° C. overnight under N2. The reaction mixture was partitioned between brine and EtOAc. The organic layer was dried (sodium sulfate), evaporated, and purified by flash chromatography (silica, 30% EtOAc/hexanes) to give compound 4c (348 mg, 32.3%). MS (CI) m/z 502.2 (MH+-Boc).
