ChEBI: 4-morpholinyl-(3,4,5-trimethoxyphenyl)methanone is a member of morpholines.

46 g 3,4,5-trimethoxybenzoyl chloride are dissolved in 300 ml anhydrous benzene and 25 g triethylamine and thereafter 19 g anhydrous morpholine are added in small portions with ice-cooling. The solution is boiled for 2 hours under reflux. The precipitate is filtered off, and the solution is washed with dilute sulfuric acid, then with sodium hydrogen carbonate solution and finally with water, and then evaporated. The residual yellow oil soon crystallizes; the crystalline mass of the desired material is taken up with ether, filtered and then recrystallized from 90% ethanol, from which it separates in prisms. It is slightly soluble in water. Yield: 80%. melting point 120°C to 122°C.
