Reaction Steps

4-Amino-2-chloropyridine (0.103 g, 1.802 mmol), triethylamine (0.0812 g, 0.802 mmol) and 2-chloro-1,3-dimethylimidazolinium chloride (0.136 g, 0.802 mmol) were added to a methylene chloride solution (100 ml) of 5-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzoic acid (0.200 g, 0.535 mmol) and the resulting solution was stirred in an oil bath at 50° C. for 8 hours. The reaction solution was poured into ice water and then extracted with methylene chloride. The extract was washed with water and then dried, and the solvent was removed by distillation. The obtained residue was purified by preparative thin-layer chromatography (chloroform:methanol=10:1) to obtain the titled compound (0.078 g, 0.161 mmol, 30%).
