PROCEDURE

实验过程

A mixture of 2-bromo-5-formylpyridine (500 mg, 2.6 mmol), methyl acrylate (0.6 ml, 6.5 mmol), tri-(o-tolyl)phosphine (80 mg, 0.26 mmol), allyl palladium (II) chloride dimer (47 mg, 0.13 mmol) and sodium acetate (1.08 g, 8 mmol) in DMF (10 ml) was heated at 170° C. in a microwave reactor for 0.75 h. The reaction mixture was filtered through Celite® then diluted with DCM and water. The organic phase was dried, concentrated in vacuo and purified by chromatography to give the title compound as a white solid (50 mg). δH (CDCl3, 250 MHz) 10.14 (1H, s), 9.09 (1H, d), 8.19 (1H, dd), 7.72 (1H, d), 7.57 (1H, d), 7.08 (1H, d), 3.85 (3H, s). MS (ES): MH+ 192.
