Procedure

4-Nitrophenyl N-methyl-(4-(1-methylcarbamoyl-indol-5-yloxy)pyridin-2-yl)carbamate (105 mg, 0.228 mmol) was dissolved in N,N-dimethylformamide (2.5 ml); aqueous ammonia (0.5 ml, 28.0%) was added thereto; the reaction mixture was stirred at room temperature for 10.5 hours. The reaction mixture was partitioned between ethyl acetate and water; and the organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained crystals were suspended in ethanol:diethyl ether=1:1 (6 ml), filtered off, washed with diethyl ether, and dried to yield the title compound (37 mg, 0.11 mmol, 48%) as pale yellow crystals.
