Ethanolamine → HCID 54522853, compound

Participants

Reaction Steps

14.5 g of Intermediate A and 15.3 g of ethanolamine were mixed and made to react with each other over a period of 2 hours under a pressure reduced to 30 mm Hg inside the reaction container and a temperature kept at 120° C. outside the reaction container. After cooling to room temperature, the reaction product was dissolved in 30 ml of ethanol, and separated out in a crystallized condition upon addition of 300 ml of isopropanol. After filtration, the crystals were washed with isopropanol, and dried. Thus, 13 g (yield: 86.5%) of Intermediate C was obtained. Melting Point: 215°-219° C. (decomposed).
