実験手順

The reaction was carried out in a manner similar to Reference Example 18 a) except for using 8.00 g (22.0 mmol) of ethyl 7-benzyloxy-4-trifluoromethyl-2-indolecarboxylate, 0.88 g (22.0 mmol) of 60% sodium hydride, 6.25 g (44.0 mmol) of methyl iodide and 150 ml of dimethylformamide. Ethyl 7-benzyloxy-1-methyl-4-trifluoromethyl-2-indolecarboxylate was thus obtained in the yield of 7.40 g (89.1%).
