Reaction Conditions

Reaction Steps

To a sealed tube was added 3-chloro-6-methoxy-1,2-benzisoxazole (2.0 g) and N-methylethylenediamine (4.8 g). The reaction was heated to 140° C. over 48 hours and then cooled to room temperature. The residue was partitioned between EtOAc and brine, washed with brine (4×) and the organic phase was dried over MgSO4 and concentrated in vacuo. Flash chromatography (silica gel) eluting with 5% acetone/CH2Cl2 provided a residue upon evaporation (0.4 g) m.p. 136-137° C.
