Carbon Disulfide → 9-[(4-fluorophenyl)methyl]-N-[1-(2-isothiocyanatoethyl)-4-piperidinyl]-9H-purin-8-amine

Participants

Reaction Steps

To a stirred and cooled (-10° C.) mixture of 5.6 parts of N,N'-methanetetraylbis[cyclohexanamine], 13.9 parts of carbon disulfide and 90 parts of tetrahydrofuran were added portionwise 10 parts of N-[1-(2-aminoethyl)-4-piperidinyl]-9-[(4-fluorophenyl)methyl]-9H-purin-8-amine. Upon completion, the temperature was allowed to rise to room temperature and the reaction mixture was evaporated, yielding 16 parts of 9-[(4-fluorophenyl)methyl]-N-[1-(2-isothiocyanatoethyl)-4-piperidinyl]-9H-purin-8-amine (compound 181).
