반응 단계
Dimethylaminoethylchloride hydrochloride (1.5 g) was added to 2,2-dimethyl-4-(4-trifluoromethylphenylchroman-7-ol (1.0 g), potassium carbonate (4.0 g) and potassium iodide (1.5 g) in acetone (50 ml) and the mixture refluxed for 2 days. The mixture was filtered and the acetone was evaporated under reduced pressure. The resulting crude oil was chromatographed on alumina. Elution with ether:petrol (1:1) gave a clear oil which after dissolution in dry ether and passage of dry hydrogen chloride through the solution yielded the required chroman as the hydrochloride salt (0.35 g), m.p. 200°-203° C.
