Procedure

A solution of 4-({1-[2-(5-methoxycarbonyl-1methyl-1H-pyrrol-3-ylcarbamoyl)-1H-indol-5-yl]-methanoyl}-amino)-1-methyl-1H-pyrrole-2carboxylic acid methyl ester 8 (1.04 g, 2.18 mmole) and NaOH (10 mmole) in a mixture of water/MeOH (1/4) (25 ml) was stirred at 50C. for 6 h and then overnight at ambient temperature. The reaction mixture was evaporated in vacuo to dryness and the residue was dissolved in water (50 ml) and acidified with 1M HCl up to pH=3. The precipitate was collected on the filter and washed with water (3×50 ml) and dried over phosphorus pentoxide in dessicator to give 0.85 g (87%) of 4-({1-[2-(5-hydroxycarbonyl-1-methyl-1H-pyrrol-3-ylcarbamoyl)-1H-indol-5-yl]-methanoyl}-amino)-1-methyl-1H-pyrrole-2-carboxylic acid 9 as white crystalline material. MS: 448.08 (M−H). 1-NMR (DMSO-d6): 11.96 (s, 1H, H-1, indole); 10.45&10.25 (s&s, 1H&1H, —C(═O)NH); 8.30 (m, 1H, H-6, indole); 7.48 (m, 3H with *, H-7, indole); 7.49&7.46 (d&d, *, H-3 or H-5, Py1&Py2); 7.39 (s, 1H, H-3, indole); 6.91 (m, 2H, H-3 or H-5, Py1&Py2); 3.84&3.83 (s&s, 6H, NCH3, Py1&Py2).
