Reaction Steps

3-(4-morpholinylmethyl)-6-(4-methoxybenzoyl)-2,3-dihydropyrrolo[1,2,3-de]-1,4-benzoxazine, m.p. 209°-214° C. (1.5 g from ethyl acetate) was prepared by reaction of 13 g (0.052 mole) of 3-(4-morpholinylmethyl)-4-amino-3,4-dihydro-2H-1,4-benzoxazine with 10.2 g (0.057 mole) β-(4-methoxyphenyl)-β-ketopropionaldehyde in glacial acetic acid (the β-ketopropionaldehyde being prepared by reaction of 4-methoxyacetophenone with methyl formate in diethyl ether in the presence of ethanol and sodium hydride).
