Procedure

A suspension of methyl [3,5-di-(2-chlorobenzyloxy)benzoyl]aminobenzene-3-carboxylate (455 mg, 1.04 mmol) in THF was treated with sodium hydroxide solution (0.85 ml of 2M, 1.7 mmol), and the reaction stirred at ambient temperature, with tlc monitoring. Methanol (3 drops) and further additions of sodium hydroxide solution (2×0.85 ml of 2M, 3.4 mmol) were made, until complete hydrolysis was achieved. The resulting solution was diluted with water (30 ml) and acidified to pH1 (2M HCl); the precipitate thus formed was filtered off, washed (water) and dried to give the title compound as a colourless solid, 328 mg, 1H NMR δ (d6-DMSO): 5.25 (4H, s); 7.0 (1H, s); 7.4 (6H, m); 7.5 (2H, m); 7.6 (2H, m); 8.2 (1H, d).
