Reaction Steps

15.0 g (81 mmol) of (2,6-dichlorophenyl)acetonitrile in 60 ml of ethanol were admixed with 10.3 g (148 mmol) of hydroxylamine hydrochloride and then with 11.1 g (105 mmol) of sodium carbonate dissolved in 40 ml of water. This mixture was refluxed for 4 h, poured into aqueous sodium dihydrogen phosphate buffer (pH 7–8) and extracted with methylene chloride. The resulting white solid precipitate (14.0 g) was filtered off and dried under reduced pressure. More product (3.1 g) was obtained from the extract after removal of the solvent under reduced pressure. The overall yield was 17.1 g, m.p. 172–173° C.
