摘要:
The present invention relates to a process for preparing a 5-(N-substituted)aminomethyl-1-benzocycloalkyl-1,3-dihydroimidazole-2-thione (wherein the N-substituent is selected from formyl, aminocarbonyl, (C.sub.1-4)alkylcarbonyl or trifluoro (C.sub.1-4)alkylcarbonyl), which process comprises reacting a benzocycloalkylamine with thiocyanic acid and dihydroxyacetone to give a corresponding 5-hydroxymethyl-1-benzocycloalkyl-1,3-dihydroimidazole-2-thione and then reacting the 5-hydroxymethyl-1-benzocycloalkyl-1,3-dihydroimidazole-2-thione with a compound of the formula H.sub.2 NC(0)R.sup.2 in which R.sup.2 is hydrogen, amino, (C.sub.1-4)alkyl or trifluoro(C.sub.1-4)alkyl or with an ammonium salt of the formula NH.sub.4.sup.+ - OC(0)R.sup.3 in which R.sup.3 is hydrogen, (C.sub.1-4)alkyl or trifluoro(C.sub.1-4)alkyl.The present invention also relates to a process for preparing 5-aminomethyl-1-benzocycloalkyl-1,3-dihydroimidazole-2-thiones, which process comprises preparing a 5-(N-substituted)aminomethyl-1-benzocycloalkyl-1,3-dihydroimidazole-2-thione (wherein the N-substituent is selected from formyl, (C.sub.1-4)alkylcarbonyl or trifluoro(C.sub.1-4)alkylcarbonyl) by the process described above and then hydrolyzing with acid.
