Procedure
7N ammonia/methanol (30 mL) and Raney nickel (500 mg) were added to 5-(4-fluorobenzyl)thiophene-2-carbaldehyde described in Preparation Example 37 (460 mg, 2.09 mmol), and the mixture was stirred for 14 hours under hydrogen atmosphere at room temperature. The catalyst was removed by filtering through Celite pad, then, purification by silica gel column chromatography (ethyl acetate, then ethyl acetate:methanol=4:1) was carried out, and the title compound (70 mg, 0.316 mol, 15.1%) was obtained as an oil.
