Procedure

Add concentrated ammonium hydroxide (2 mL) to a solution of (5,6-Dihydro-4H-pyrrolo[3,2,1-ij]quinolin-1-yl)oxoacetic acid methyl ester (0.50 g, 2.06 mmol) in 10 mL of tetrahydrofuran at 0° C. Remove the cooling bath and stir the mixture for 3 hours. Dilute the reaction with 20 mL of water and filter the suspension. Wash the filter cake with 10 mL of water followed by 10 mL of diethyl ether, and dry under reduced pressure to provide the desired compound as a light yellow solid (0.403 g, 86%).
