Reaction Steps

A suspension of 184 mg of the compound of Step D in 10 mL of ethanol was treated with 0.5 mL of 55% hydrazine hydrate and refluxed for 1 hour. Solids in the cooled reaction mixture were filtered off and discarded and the filtrate was evaporated to a gum which was triturated with ether and filtered. The filtrate was again evaporated to a foam which was shown to be 104 mg of the analytically pure title compound. Anal. Calcd. for C18H13O2N3Cl4 : C, 48.57; H, 2.94; N, 9.44. Found, C, 48.41; H, 2.52; N, 9.43.
