Reaction Conditions

Reaction Steps

35.96 ml of triethylamine (258 mmol), followed by a solution of 14 g of methoxyacetyl chloride (Aldrich, 129 mmol) in 250 ml of dichloromethane, are added to a solution of N-methyl-O-methylhydroxylamine hydrochloride in 250 ml of dichloromethane cooled to 0° C. The mixture is stirred for 3 hours while allowing it to return to ambient temperature. A 1N solution of HClaq is added and then the organic phase is washed with water, dried over sodium sulphate, filtered, and concentrated under vacuum. 13.14 g of expected product are obtained in the form of an oil which is used without subsequent purification (crude yield=76%).
