참여 물질

반응 단계

0.23 g of sodium are dissolved in 30 ml of 1-heptanol at 50° under nitrogen. Dropwise, with stirring, there is added 4.88 g of N-heptyl-N-methyl-2-bromo-4,5-bibenzyloxycyclopentane-1-amine (obtainable from 3,5-dibenzyloxy-2-cyclopentene by the addition of bromine and reaction with 1-equivalent of methyl heptylamine), dissolved in 30 ml of benzene. Stirring is carried on for 6 hours at 50°. After cooling, 100 ml of benzene is added thereto. This is washed with water. The organic phase is dried over MgSO4 and the solvent is distilled off. After chromatographic purification of the residue (silica gel/chloroform:acetone=9:1), N-heptyl-N-methyl-5-heptyloxy-2,4-dibenzyloxy-cyclopentane-1-amine is obtained.
