Reaction Steps

A suspension of 2-(4-chlorophenyl)-6-hydroxy-4-methyl-2H-1,2,4-benzothiadiazine-3(4H)-one 1,1-dioxide (250 mg), potassium carbonate (122 mg) and bromomethylyclohexane (159 mg) in N,N-dimethyl formamide (1 ml) was stirred for 2 hours at 60° C. The mixture was poured into ice water. The separator solid was collected by filtration, dried, and recrystallized from ethanol to yield 2-(4-chlorophenyl)-4-methyl-6-cyclohexylmethoxy-2H-1,2,4-benzothiadiazine-3(4H)-one 1,1-dioxide (230 mg).
