Versuchsvorschrift

5-Amino-2-methyl-1,2,3,4-tetrahydroisoquinoline (5.0 g) prepared as in Example 4 was dissolved in dry benzene (75 ml) and 0.5 g of dry potassium bicarbonate was added. A 0.1 mole excess of 2-fluorobenzoyl chloride was dissolved in dry benzene (75 ml) and this solution was added to the solution of the tetrahydroisoquinoline. A white precipitate formed immediately. The mixture was refluxed for 1 hour to insure that the reaction had gone to completion. The precipitate was collected by vacuum filtration and washed with 10% sodium carbonate solution followed by water. The washings were discarded and the remaining residue was recrystallized from ethyl acetate to yield 6.8 g of the desired product as white crystals, m.p. 112°-112.5° C.
