Procedure
Operation was carried out in a manner similar to the one previously described in Example 5, using 10.4 g of 1-(2-hydroxyethyl)piperazine and 6.3 g of 2-chloronicotinic acid in 100 ml dioxane under reflux for 18 hours. Grams 3.9 of 2-[4-(2-hydroxyethyl)piperazin-1-yl]nicotinic acid, melting at 148°-171° C. (with decomposition), were obtained.
