Reaction Steps

2-Pyridylhydrazine (10.9 g) in dichloromethane (120 ml) and dry triethylamine (28 ml) were chilled in an ice bath. -β-chloropivaloyl chloride (15.5 g) in dichloromethane (20 ml) was added dropwise with stirring for 15 minutes and the mixture was refluxed for 3 hours. When cool the triethylamine hydrochloride was filtered off and the filtrate evaporated to dryness and rinsed four times with the minimum quantity of ether to give the title compound (13.6 g) after recrystallisation from cyclohexane mp 141°-144°.
