Procedure
9.4 g (0.038 mol) of 1-[p-(2-methoxycarbonylaminovinyl)-phenoxy]-2,3-epoxy-propane are dissolved in 200 ml of isopropanol, 3.25 ml (0.038 mol) of isopropylamine are added and thereafter the mixture is heated to the boil for 3 hours, under a reflux condenser. It is then evaporated in vacuo and the resulting crude base is crystallised from acetone-ether. 1-[p-(2-Methoxycarbonylaminovinyl)-phenoxy]-2-hydroxy-3-isopropylamino-propane of melting point 128°-129° C. is obtained.
