(0.06 mole) of 2-trifluoroacetyl-7-fluorosulfonyl-1,2,3,4-tetrahydroisoquinoline and 100 ml. of acetone and 50 ml. of 6 N hydrochloric acid was stirred at room temperature overnight. The solution was concentrated, taken up in water, extracted with chloroform, concentrated and the water azeotropically removed.
