실험 절차

To a mixture of 4-(5-chloro-furan-2-ylmethyl)-benzylamine (2.6 g) described in Manufacturing Example 62-1-2, acetic acid (25 mL) and water (25 mL) was added sodium nitrite (9.8 g, 140 mmol) at 0° C., which was stirred for 40 minutes at room temperature. Water and ethyl acetate were added to extract the reaction mixture. The organic layer was washed successively with water, saturated sodium hydrogencarbonate and saturated aqueous sodium chloride, and the solvent was evaporated under a reduced pressure. Methanol (25 mL) was added to the residue at 0° C., followed by addition of potassium carbonate (3.3 g, 24 mmol) at the same temperature. This was stirred for 1 hour at the same temperature. Water and ethyl acetate were added to extract the reaction mixture. The organic layer was washed successively with water, saturated sodium hydrogencarbonate and saturated aqueous sodium chloride, and the organic layer was concentrated under a reduced pressure. The residue was purified by neutral silica gel column chromatography (ethyl acetate:heptane=1:2) to obtain the title compound (1.2 mg, 44%).
