Versuchsvorschrift

A mixture of trans-stilbene oxide (3.93 g, 0.20 mole) and 1-amino-2-propanol (4.51 g, 0.060 mole) was heated in an oil bath at 125° C. for 1 hour. After standing at ambient temperature for 18 hours, the viscous oil was dissolved in 20 ml of methanol and diluted with water causing a white solid to precipitate. The solid was collected, washed with water, and dried under ambient conditions to give 4.57 g (84%) of the product which was recrystallized from toluene to give 3.65 g solids; m.p. 116°-118° C.
