Procedure
To a stirred solution of tert-butyl 6-({3,5-di(2-cyanobenzyloxy)benzoyl}amino)pyridin-3-yl(2-methoxyethyl)carbamate (237 mg) in dichloromethane (10 ml) was added trifluoroacetic acid (3 ml). The solution was stirred at ambient temperature for three hours. Volatile material was removed by evaporation. The residue was diluted in DCM (100 ml), washed with 2M sodium Hydroxide (50 ml), brine (50 ml), dried over MgSO4. Volatile material was removed by evaporation to give the title compound (190 mg) as a foam, 1H NMR δ (d6-DMSO): 3.22 (t, 2H), 3.28 (2, 3H), 3.50 (t, 2H), 5.31 (s, 4H), 6.92 (s, 1H), 7.12 (dd, 1H), 7.34 (s, 2H), 7.57 (m, 2H), 7.75 (m, 5H), 7.82 (d, 1H), 7.91 (d, 2H), 10.49 (br s, 1H). MS ES+ 534.41 (M+H)+.
