Reaction Steps
A solution of 6.8 g of 2-[α-(2-methoxyphenoxy)-benzyl]-4-methylmorpholin-3,5-dione in 40 ml of anhydrous tetrahydrofuran was added dropwise under stirring to a suspension of lithium aluminium hydride (1.9 g) in 35 ml of THF. The mixture was refluxed under stirring for 6 hours. Dropwise addition was then made at 0°-5° C. of 4.1 ml of 23% HCl and the whole was stirred at room temperature for 2 hours. The suspended solid was filtered and washed several times with THF. The combined filtrates were evaporated to dryness under reduced pressure. The residue was taken up with ethyl ether and 4 ml of 18% methanolic HCl was added. The amorphous hydrochloride precipitated which was washed several times with fresh ethyl ether. By filtration there was obtained 5.8 g of 2-[α-(2-methoxyphenoxy)-benzyl]-4-methyl-morpholine hydrochloride, melting point 67°-90° C. Yield 84%.
