Procedure

2-(2,2,2-Trifluoro-acetyl)-1,2,3,4-tetrahydro-isoquinoline-7-sulfonic acid thiazol-2-ylamide (5.0 g, 0.013 mol), was suspended in EtOH (50 mL). After slowly adding KOH (3.0 g, 0.05 mol) over 5 minutes, the solution started to clear. After an additional 10 minutes of stirring, the formed precipitate was filtered, washed several times with EtOH, and dried under high vacuum to give the amine (3.0 g, 0.012 mmol, 95% yield). LC/MS (10-99% CH3CN), M/Z: M+1 obs=296.2; tR=0.66 min.
