Ammonium hydroxide (conc., 20 mL) was added to 2-acetyl-1,2,3,4-tetrahydro-isoquinoline-7-sulfonyl chloride (2 g). The mixture was stirred at rt for 16 h. The ammonium hydroxide was evaporated under vacuum and hydrochloric acid (10%, 50 mL) was added to the residue. The mixture was heated at reflux for 4 h and the aqueous was evaporated under vacuum to afford 7-aminosulfonyl-1,2,3,4-tetrahydro-isoquinoline hydrochloride (1.5 g).
