実験手順
N-(2-cyanopropan-2-yl)-5-methyl-1,3,4-oxadiazole-2-carboxamide (II) (185 gms) was suspended in isopropyl alcohol (462 ml), heated to 50 to 55° C. Aqueous hydroxylamine (IIIa; 76 ml) was added and the reaction mixture stirred for 30 minutes at 60° C. After completion, reaction mass was cooled between 0 and 5° C. and heptane (462 ml) was added to the reaction mass. The resultant slurry was filtered, washed with heptane (185 ml) and the wet cake was dried to give N-[(1Z)-1-amino-1-(hydroxyimino)-2-methylpropan-2-yl]-5-methyl-1,3,4-oxadiazole-2-carboxamide (IVa).
