Procedure

A solution of EXAMPLE 403D (500 mg), and piperazine (420 mg) in dimethylsulfoxide (9 mL) was heated at 100° C. for 3 hours. The crude product was isolated by concentration and, following an aqueous work up, it was purified on silica gel, and was eluted with a 5 and 10% methanol in methylene chloride step gradient to provide the title compound.
