The reaction solution was allowed to cool, and concentrated under reduced pressure to dryness. The resulting yellow oily product was dissolved in toluene (10 ml), and to this solution was added paratoluenesulfonate salt of (1R,2S)-2-fluorocyclopropylamine (270 mg, 1.09 mmol). The mixture was stirred at -10°C, and triethylamine (0.158 ml, 1.13 mmol) was added dropwise with stirring. The reaction solution was stirred at room temperature for 1 hour, and water (150 ml) and ethyl acetate (20 x 2 ml) were added to the solution. The solution was washed with saturated aqueous solution of sodium chloride (15 ml), and dried with anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to dryness. The yellow oily product was dissolved in dimethylformamide (5 ml), and potassium carbonate (202 mg, 1.46 mmol) was added in an ice bath, and the solution was stirred at room temperature for 4 days. To the reaction solution was added 10percent aqueous solution of citric acid (20 ml) in an ice bath, and the precipitated crystals were collected by filtration. The crystals were washed with an excess amount of purified water, and the resulting crude crystals were subjected to silica gel column chromatography to obtain 277 mg (73percent) of the title compound as pale yellow powder from the eluate of a mixed solution of chloroform and methanol (95 : 5). 1H-NMR (400 MHz, CDCl3) delta: 1.20-1.34 (2H, m), 1.41 (3H, t, J = 7.1 Hz), 1.46 (9H, s), 2.57 (3H, s), 2.88 (1H, s), 3.14-3.18 (1H, m), 3.44-3.60 (2H, m), 3.80-3.92 (2H, m), 4.39 (2H, q, J = 7.1 Hz), 4.50-4.56 (1H, m), 4.65-4.70 (1H, m), 4.74-4.82 (1H, m), 4.94-4.90 (1H, m), 7.96 (1H, d, J = 13.2 Hz), 8.53 (1H, d, J = 2.9 Hz).
