실험 절차

A solution of 3.5 g. (0.0129 mol) of N-[2-(3-methoxyphenyl)ethyl]-2-phenyl-2-hydroxyethylamine in 40 ml. of 48% hydrobromic acid is refluxed for two hours and then concentrated to dryness. The solid residue (equal mixture of 7-hydroxy and 9-hydroxy benzazepines) is chromatographed on a silica gel column, eluting with methanol in chloroform to first remove the 7-hydroxy isomer and then to yield the product 9-hydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrobromide, m.p. 134°-150° C. (int.).
