Procedure
Grams 8.65 of 1-(3-hydroxypropyl)piperazine and 4.7 g of 2-chloronicotinic acid in 100 ml dioxane were refluxed for 6 hours. The reaction mixture was cooled and settled. The residual oil, crystallized from 95° ethanol, gave 2.3 g of 2-[4-(3-hydroxypropyl)piperazin-1-yl]nicotinic acid, melting at 222°-225° C. (with decomposition).
