Reaction Steps

A mixture of 6.0 g (25 mmol) 2-acetylamino-6-chloro-isonicotinic acid ethyl ester, 10.36 g (75 mmol) potassium carbonate and 4.23 ml (50 mmol) allyl bromide in 25 ml DMF is stirred at 60° C. for 24 h. The cooled mixture is diluted with water and TBME. The organic phase is washed with water, dried over Na2SO4 and evaporated.
