Reaction Steps
A mixture of 3-chloromethylisoquinoline hydrochloride (40 g) and sodium ethoxide (40 g) in ethanol (700 cc) is heated under reflux for 8 hours. After cooling to 20° C., the mixture is filtered and the filtrate is evaporated to dryness at 50° C. under reduced pressure (20 mm Hg). The residue is taken up in methylene chloride (500 cc), the mixture is washed with water (3×100 cc), the organic phase is dried over magnesium sulphate and filtered and the filtrate is evaporated to dryness at 40° C. under reduced pressure (20 mm Hg). The oily residue is distilled at 110°-114° C. under a pressure of 0.6 mm Hg. 3-Ethoxymethylisoquinoline (31 g), a colourless oil, is obtained.
