Versuchsvorschrift

2-Amino-2-methylpropanenitrile (90 gms) was suspended in dichloromethane (90 ml) and N-methyl morpholine (1.10 moles) was added with stirring. A mixture of oxadiazole carbonyl chloride (90 gms) in dichloromethane (100 ml) was added drop wise to the suspension at 0 to 5° C. The reaction mixture was stirred and monitored by thin layer chromatography (TLC). The reaction mass was concentrated under reduced pressure after completion of reaction. The product separated out on addition of isopropyl alcohol (500 ml), which was then filtered and dried.
