Following the procedure described in Example 1, step 4, but substituting indole-2-carboxylic acid for 5, followed by Example 18, step 1, 2, 3, but substituting respectively ethyl-6-iodohexanoate for ethyl-7-iodoheptanoate and indole-2-carbonyl chloride for benzoyl chloride, and then the resulting carboxylic acid was substituted for 37 in Example 14, step 3, using 1.1 equivalent of NH2OH.HCl and triethylamine each, to afford the title compound 112 in 35% yield. 1H NMR: (300 MHz, CDCl3) δ 7.62 (m, 2H), 7.20-7.00 (m, 3H), 2.82 (m, 2H), 2.00 (m, 2H), 1.62 (m, 2H), 1.22 (m, 4H).
