A solution of 1.35 g 1,2,3,4-tetrahydroisoquinoline with 5 ml aceton was added dropwise to a suspension of 1.5 g phenylcarbamoyl-benzoic acid sulfimide with 20 ml aceton, at ambient temperature. The reaction mixture was stirred for 45 minutes, then diluted with 150 ml water, cooled to 5° C. and the precipitated crystalline product was filtered, washed with water and dried. 1.18 g N-phenylcarbamoyl-1,2,3,4-tetrahydroisoquinoline was obtained with a melting point of 145°-146° C.
