Phenol → N-(2-phenoxyethyl)propionamide

Participants

Reaction Steps

Phenol (13.1 moles) was heated to 150° and stirred under N2 as 2-ethyl-2-oxazoline (12.2 moles) was added over 1 hr. The mixture was heated to 175±3°. After heating 16 hr the oil was cooled to about 140°, and then it was poured into water (12 L) with vigorous stirring. The mixture was stirred and cooled, and at about 25° the mixture was seeded with crystalline amide product. The material solidified and the supernatant was decanted. The residual solid was stirred with 17 L of hot (85°) water. The mixture was cooled to 25°, seeded with the amide product, and the mixture refrigerated. The resulting granular solid was collected on a filter, rinsed with several portions of water and left to air dry. This gave a 92% yield of material, m.p. 61.5°-64°.
