Procedure

A suspension of 5.3 g of the compound prepared in Example 16 in 20 ml of methanol was cooled to 10° and 50 ml of concentrated hydrochloric acid was added dropwise at 10°-15° (gas evolution). The reaction mixture was allowed to warm to room temperature and then refluxed 3.75 hours. The reaction solution was cooled and concentrated in vacuo. The white solid was washed with ethanol followed by ethyl acetate then dried to give 4.1 g of 2,3-dihydro-2-methyl-1H-isoindole-4-sulfonamide hydrochloride, m.p. >250°.
