Another pathway expected to lead to the desired ethanolamines was explored briefly: 4, 4- bis (hydroxymethyl) oxa~ olidone-2~(VII. X= OH) was converted by the action of thionyl chloride to the bischloromethyl derivative (VII. X= C1) which, in turn was treated with piperidine to give the bispiperidinomet, hyloxazolidorie
