4-Oxiranylmethoxy-1,3-dihydro-2-benzimidazolone → 1-[N-benzyl-N-(6,7,8,9-tetrahydro-2-hydroxy-5H-benzocyclohepten-6-yl) amino]-3-(1,3-dihydro-2-benzoimidazolon-4-yloxy)-2-propanol

Participants

Reaction Steps

A mixture of 4-oxiranylmethoxy-1,3-dihydro-2-benzimidazolone (82.5 mg) and N-benzyl-(6,7,8,9-tetrahydro-2-hydroxy-5H-benzocyclohepten-6-yl)amine (107 mg) in ethanol (1.5 ml) was stirred under reflux for 13 hours, cooled to room temperature and evaporated in vacuo. The residue was chromatographed (dichloromethane-methanol)by silica gel (4.2 g) to afford 1-[N-benzyl-N-(6,7,8,9-tetrahydro-2-hydroxy-5H-benzocyclohepten-6-yl)amino]-3-(1,3-dihydro-2-benzoimidazolon-4-yloxy)-2-propanol (123 mg) as a colorless powder.
