实验过程

To a microwave vial was added Pd(tBu3P)2 (128 mg, 0.250 mmol) and difluorozinc (259 mg, 2.50 mmol). The vial was capped and purged with nitrogen for 10 minutes. DMF (1 mL) was added and the mixture was stirred for 10 minutes. A solution of (4-bromo-3-methoxy-phenyl)-(7′-chlorospiro[piperidine-4,4′-pyrrolo[2,1-c][1,4]benzoxazine]-1-yl)methanone (244 mg, 0.500 mmol) in DMF (1.5 mL) was added followed by trimethyl(vinyloxy)silane (581 mg, 5.00 mmol). The reaction mixture was heated at 80° C. for 1 h before it was quenched with brine and extracted with EtOAc (3×). The combined organic layers were dried over sodium sulfate and the solvent was removed. The crude reaction was purified by silica gel chromatography (5%-80% ethyl acetate/hexanes) to give 2-(4-(7-chlorospiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-1′-ylcarbon-yl)-2-methoxyphenyl)acetaldehyde.
