実験手順
The reaction was carried out in a manner similar to Reference Example 18 b) except for using 7.71 g (22.4 mmol) of ethyl 7-benzyloxy-4-chloro-1-methyl-2-indolecarboxylate, 0.50 g of 10% palladium/carbon and 150 ml of tetrahydrofuran. Ethyl 4-chloro-7-hydroxy-1-methyl-2-indolecarboxylate was thus obtained in the yield of 4.70 g (82.6%).
