Reaction of 4-(3-Trifluoromethylphenyl)-2,2-dimethyl-7-chromanol with epichlorohydrin, by an analogous method to that described in Example 1, gave 7-(2,3-epoxypropoxy)-4-(3-trifluoromethylphenyl)-2,2-dimethylchroman. Reaction of this epoxide with methylamine, by an analogous method to that described in Example 2 gave 4-(3-trifluoromethyl-phenyl-7-(2-hydroxy-3-methylaminopropoxy)-2,2-dimethylchroman, (benzoate salt, m.p. 145-157°).
