Procedure
Twenty six grams (g) (162 millimoles (mmol)) of commercially available 2-benzofuranylmethylketone was dissolved in 300 milliliters (ml) of methanol, and 16.9 g (243 mmol) of hydroxylamine hydrochloride and 20.4 g (243 mmol) of sodium hydrogencarbonate were added thereto. The resulting mixture was stirred at room temperature for 8 hours. Then, φml of water was added and the methanol was distilled away under reduced pressure. Precipitated crystals were filtered off and washed with water to yield 27.8 g of 2-benzofuranylmethylketone oxime having the following formula (yield, 98%). ##STR26##
