実験手順
4.2 g of (-)-1-amino-3-(o-ethoxyphenoxy)-propan-2-ol (laevo-rotatory) ##STR38## are dissolved in 30 ml of ethanol, 3.3 g of the nicotinoyl-acetone ##STR39## are then added and the mixture is heated for 4 hours under reflux, with addition of 1 drop of formic acid as the catalyst. The clear solution is cooled to room temperature and concentrated in a water pump vacuum. An oil is left, which solidifies after a short time. The solid product is recrystallised from toluene. (-)-1-(2-Nicotinoyl-1-methyl-vinylamino)-3-(o-ethoxyphenoxy)-propan-2-ol (laevo-rotatory) is thus obtained ##STR40##
