Versuchsvorschrift
Operation was carried out in a manner similar to the one described in Example 2, using 1.6 g of 2-chloronicotinamide, 3.2 g of 1-(2,3-dihydroxypropyl)piperazine and 30 ml ethanol and refluxing overnight. Column purification of the residue gave 1 g of 2-[4-(2,3-dihydroxypropyl)piperazin-1-yl]nicotinamide, which, recrystallized from acetone, melted at 140°-142° C.
