Reaction Steps

A mixture of 7-(2,3-epoxypropoxy)-2,2-dimethyl-4-phenylchroman (6.1g), anhydrous dimethylamine (15ml) and ethanol were left to stand at ambient temperature until tlc showed that reaction was complete (c. 2hrs.). Removal of the solvent in vacuo gave 7-(2-hydroxy-3-dimethylaminopropoxy)-2,2-dimethyl-4-phenylchroman (6.8g, 97%) isolated as the hydrochloride salt, m.p. 210°-215°, from acetone-ethanol.
