Abstract
PURPOSE: To prepare acetimide ether hydrochloric acid salt useful as raw materials for medical intermediates, if the form of a stable, homogeneous, and easily handleable solution, by reacting acetonitrile with methanol or ethanol and hydrogen chloride at a specific mixing ratio.
CONSTITUTION: A homogeneous solution containing acetimide ether hydrochloric acid salt is prepared by reacting 1 mole of acetonitrile with 0.3W0.6mol of methanol or ethanol and 0.5W1.5mol of hydrogen chloride (the molar ratio of hydrogen chloride to the alcohol is pref. ≥1), at -30W150°C, preferably at -10W60°C, most preferably at -5W10°C. The raw material acetonitrile is preferably sufficiently dehydrated before use, with a dehydrating agent, e.g. phosphorus pentoxide, molecular sieve, magnesium sulfate, etc.
