実験手順

5-Isothiocyanato-3-propylisoquinoline (4.5 g) is added to a solution of (RS)-3-(2-hydroxyethyl)-1,2,3,4-tetrahydroisoquinoline (3.5 g) in absolute ethanol (35 cc). After stirring for 20 hours at a temperature of about 20° C., the crystals which have appeared are filtered off and then washed with ethanol (2×2 cc). (RS)-3-(2-Hydroxyethyl)-N-(3-propylisoquinol-5-yl)-1,2,3,4-tetrahydroisoquinoline-2-carbothioamide (5.7 g) is thus obtained; after recrystallisation from propanol (50 cc), it melts at 175° C.
