Reaction Steps

17.5 g (0.10 mole) 2-cyanomethyl-1,4-benzodioxane, prepared as described by Augstein, et al., J. Med. Chem. 8: 446 (1965), was dissolved in a mixture containing 7 g ethanol and 50 ml diethyl ether. 4.5 g (0.15 moles) of dry HCl was bubbled though the mixture, which was then capped. The mixture was allowed to stand at 5° C. for 4 days, followed by 3 days at room temperature. The crude product imidate hydrochloride (IV) precipitated out and was harvested by filtration, and washed with 100 ml ether, followed by 3×100 ml portions of methylene chloride. The solid was then purified by thin layer chromatography using 10% methanol in chloroform as a developing solvent. The product has an Rf value of 0.7-0.8; starting material moves farther in this solvent system, and none was present in the crude product. The yield of product was 15.3 g, as the hydrochloride, or 59% yield.
