合成路线1
该中间体在本合成路线中的序号：(X)The selective hydrolysis of 1,4-diacetoxy-5,6,7,8-tetrahydro-5,8-ethanonaphthalene (VII) with diethylamine in methanol gives 4-acetoxy-5,6,7,8-tetrahydro-5,8-ethano-1-naphthol (VIII), which is condensed with epichlorohydrin (III) by means of piperidine at 90 C to afford 1-acetoxy-4-(2,3-epoxypropoxy)-5,6,7,8-tetrahydro-5,8-ethanonaphthalene (VII). The reaction of (IX) with tert-butylamine (V) in refluxing toluene gives 1-acetoxy-4-[3-(tert-butylamino)-2-hydroxypropoxy]-5,6,7,8-tetrahydro-5,8-ethanonaphthalene (X), which is finally hydrolyzed with dry HCl in refluxing methanol
