Conditions

Temperature: 100 °C

Procedure

To a solution of EXAMPLE 342D (650 mg) in dimethylsulfoxide (12 mL) was added piperazine (618 mg). The solution was heated at 100° C. for one hour, cooled, added to dichloromethane, extracted with water three times, dried over anhydrous sodium sulfate, filtered, and the solvent was removed under vacuum.
