88.F STEP F. Intermediate 88F. Preparation of N'-hydroxypivalimidamide

To a stirred solution of pivalonitrile (20 g, 241 mmol) in ethanol (200 mL) was added 50% aqueous hydroxylamine (73.7 mL, 1203 mmol) and refluxed for 1 h. The reaction mixture was concentrated under reduced pressure and the residue was diluted with water. The mixture was stirred for 15 min and the solids were filtered off. The product was dried under high vacuum to afford (E)-N'-hydroxypivalimidamide (22 g, 189 mmol, 79% yield) as white solid. MS (ESI) 117 (M+H).
