Procedure

A solution of EXAMPLE 377E (0.230 g) and piperazine (0.255 g) in dimethylsulfoxide (3 mL) was heated to 85° C. for 1 hour. The reaction was cooled and diluted with ethyl acetate (75 mL). The organic layer was washed with water (3×50 mL) and brine (50 mL), dried over magnesium sulfate, filtered, and concentrated to give the title compound.
