Procedure

3-Methoxy-2,5-dioxo-2,5-dihydro-1H-benz[b]azepine (1.0 g) was treated with diethanolamine (10 mL), and the mixture was heated to 140° C. for 2 hours. The mixture was diluted with water and extracted with ethyl acetate. The combined organic extracts were washed with brine, dried and evaporated. The solid was recrystalized from ethanol to give the title compound (53 mg); mp 204°-205° C.; NMR: 5.90 (s,1); MS: m/z=277(+1). Analysis for C14H16NO4 : Calculated: C, 60.80; H, 5.84; N, 10.14; Found: C, 61.29; H, 5.29; N, 11.74.
