125 °C

A mixture of styrene oxide (2.40 g, 0.020 mole) and ethanolamine (1.22 g, 0.020 mole) was heated at 125° C. in an oil bath for 2 hr. An NMR analysis showed no styrene oxide remaining. On standing at ambient temperature for 16 hrs, partial solidification occurred. The material was triturated with ethyl acetate, giving a white solid which was collected by filtration and washed with isopropyl ether. A small amount of second crop was obtained from the filtrate for a total of 0.82 g (23%). Recrystallization from ethyl acetate-isopropyl ether gave 0.69 g of a white solid, m.p. 96°-98° C.
