温度

0 °C

The compound of Example 1 (c) (0.500 g, 0.922 mmol) was dissolved in anhydrous ether (10 ml) and diethylzinc (1.0M solution in hexanes, 1.84 ml, 1.84 mmol) was added. The solution was cooled to 0° C. and diiodomethane (0.15 ml 1.84 mmol) was added. The reaction was diluted with ethyl acetate (50 ml) and washed with saturated aqueous ammonium chloride solution. The organic layer was dried over (MgSO4) and evaporated. The residue was purified by chromatography on silica eluting with 5% ethyl acetate/hexanes→10% ethyl acetate/hexanes. The product obtained was left standing in HCl/ether for 16 h. The solvent was removed in vacuo and the title compound suspended in ether and filtered. 1H NMR (DMSO-d6) δ 7.90 (1H, s), 7.50 (2H, s), 7.29-7.40 (5H, m), 3.36 (2H, s), 3.17 (2H, m), 2.74 (2H, m), 2.30 (2H, m), 2.01 (2H, m), 1.13 (4H, m).
