Procedure

Methyl 3-[(6-methyl-5,11-dioxo-6,11-dihydro-5H-indeno[1,2-c]isoquinolin-3-yl)amino]-3-oxopropanoate (10, 158 mg, 0.42 mmol) was dissolved in methanol (20 mL) and dimethylformamide (2 mL). A solution of sodium hydroxide (103 mg) in water (2 mL) was added dropwise and the reaction mixture was stirred at room temperature for 24 h. Concentrated hydrochloric acid (1 mL) was added and the solution diluted with chloroform (30 mL). A dark-red precipitated was formed between the two phases. The solid was filtered and the organic and water layers discarded. The solid was washed with water (10 mL) and ether (2×10 mL). The solid was dried and compound 15 was obtained as a reddish-brown solid (93 mg, 61%): mp 262° C. (dec).
