Participants

Reaction Steps

α-(Methoxyimino)-α-(1-hydroxy-1,2,5,6-tetrahydropyridin-3-yl)acetonitrile (E2) (0.5 g, 0.0028 moles) was dissolved in dry tetrahydrofuran (20 ml) and treated with triethylamine (0.43 ml, 0.0031 moles) with stirring at room temperature. This mixture was then treated with acetyl chloride (0.22 ml, 0.0031 moles) and stirred at ambient temperature for 2 h. The mixture was filtered and the filtrate evaporated to dryness. The residue was chromatographed on silica gel eluting with chloroform. The crystalline residue was recrystallised from 60-80 petrol to give the title compound (E10) as an off-white crystalline solid (0.234 g, 38%) m.p. 87°-8° C.
