実験手順

2.58 g of 5-bromo-2-methoxy-3-pyridinecarboxaldehyde was dissolved in 30 ml of dichloromethane, a mixture of 9 ml of trimethyl orthoformate and montmorillonite K-10 (3 g) was added thereto, and the mixture was stirred at room temperature for 2 hours. After filtering the reaction solution, the filtrate was evaporated. To the residue was added ethyl acetate, followed by filtering through alumina. The filtrate was evaporated, to give 3.09 g of the title compound as a yellow oil.
