Procedure

A mixture of 4.50 g (18.0 mmol) of the compound of Step A and 2.81 g (19.0 mmol) of phthalic anhydride in 40 mL of glacial acetic acid was refluxed for 4 hours and stirred overnight at room temperature. About two volumes of water were added dropwise and the resulting solid was filtered and washed with water. The damp solid was taken up in a little ethanol, filtered and washed with a little ethanol and ether, and air dried to give the title compound, 5.11 g (69%), m.p. 295-298° C.(dec). Anal. Calcd. for C17H8O3N3Cl3 : C, 49.97; H, 1.97; N, 10.28. Found: C, 49.28; H, 1.95; N, 10.06.
