Procedure

A 500 mL 3 necked flask equipped thermometer, pressure equalised dropping funnel, nitrogen bubbler and magnetic stirrer bar was charged with 1-(2-chloroethyl)-3,4-dihydro-3-(1-methylethyl)-6-methylthio-1H-2,1,3-benzothiadiazine-2,2-dioxide (10.0 g, 0.0299 mol) and chloroform (200 ml). To this solution was added in one portion m-chloroperbenzoic acid (20.6 g, ˜4 equivalents, nominal purity 56-86%), this resulted in an exotherm which raised the temperature from 20° C. to 50° C. This solution was then stirred for 15 mins, water (100 ml) was added then 2M sodium hydroxide (100 ml). The organic layer was separated, washed again with 2M sodium hydroxide (100 ml), then water (100 ml) dried (MgSO4), filtered and the filtrate evaporated under reduced pressure to leave a white-cream foam, which was dried at 45° C. in vacuo to yield the product.
