Versuchsvorschrift
A mixture of 42.5 parts of N4 -(2-furanylmethyl)-4,5-pyrimidinediamine, 50.5 parts of ethyl 4-isothiocyanato-1-piperidinecarboxylate and 630 parts of tetrahydrofuran was stirred for 48 hours at reflux temperature. After cooling, the product was filtered off, washed with tetrahydrofuran and 1,1'-oxybisethane and dried, yielding 86.4 parts (96.2%) of ethyl 4-[[[[4-[(2-furanylmethyl)amino]-5-pyrimidinyl]amino]thioxomethyl]-amino]-1-piperidinecarboxylate (interm. 31).
