Versuchsvorschrift

This compound was prepared in accordance with Example 1 using 7.6 g of the hydrochloride of ethyl 3-aminopropanoate, 4.5 g of 3-(3-methoxyphenoxy)-1,2-epoxypropane, and 2.0 g of NaOH. The crude product was washed with 150 ml of water and dissolved in 100 ml of water and 10 ml of 2-n HCl. This solution was extracted with ethyl acetate, treated with NaHCO3, and extracted with CH2Cl2. The organic layer was separated, dried over MgSO4, filtered and evaporated. Ethyl N-[3-(2-cyano-4-methoxyphenoxy)-2-hydroxypropyl]-3-aminopropanoate crystallized. Yield 1.2 g. Melting point 72° C. (base). The structure was determined by NMR.
