実験手順

3-Chloro-6-methoxy-1,2-benzisoxazole (5.0 g, 27.2 mml) and homopiperazine (8.2 g, 81.6 mmol) were combined and mechanically stirred under N2 at 140° C. for 45 minutes. The reaction mixture was cooled to room temperature, dissolved with EtOAc (500 ml), and the solution was washed with water, brine, dried over MgSO4, and concentrated in vacuo. Flash column chromatography (silica gel, 20% MeOH/CH2Cl2) provided the product (2.0 g, m.p. 74-75° C.
