Procedure
2-Acetyl-7-chlorosulfonyl-1,2,3,4-tetrahydroisoquinoline was reacted with a concentrated aqueous solution of methylamine with cooling. The resulting solid was filtered and washed with water to give 2-acetyl-7-methylsulfamoyl-1,2,3,4-tetrahydroisoquinoline. Hydrolyzing in refluxing 10% hydrochloric acid by the procedure of Example 15 and then recrystallizing from methanol/ether gave 7-methylsulfamoyl-1,2,3,4-tetrahydroisoquinoline hydrochloride, m.p. 238°-240° C.
