5-Isothiocyanatoisoquinoline (5.1 g) is added to a solution of (RS)-6-hydroxymethyl-4,5,6,7-tetrahydrothieno[3,2-c]pyridine (4.3 g) in absolute ethanol (55 cc). After 48 hours at a temperature of about 20° C., the resulting crystals are filtered off, washed with diisopropyl ether (75 cc) and then dried at 40° C. under reduced pressure (0.1 mm Hg; 0.013 kPa). (RS)-6-Hydroxymethyl-5-[(isoquinol-5-yl)thiocarbamoyl]-4,5,6,7-tetrahydrothieno[3,2-c]pyridine (6.7 g), melting at 185° C., is thus obtained.
