An analgesic ketone, 4 : 4-diphenyl-6-N-morpholino-heptan-3-one, is produced by interaction of 2 : 2 - diphenyl - 4 - N - morpholinovaleronitrile and an excess of an ethyl magnesium halide in an inert solvent, e.g. for several hours at 75 DEG to 120 DEG C.; the ketone may then be converted into a water-soluble salt. Preferably at least two mols. of the Grignard reagent are used to one of the nitrile, and the solvent has a boiling point not substantially less than 100 DEG C. (e.g. benzene, toluene, dibutyl ether or mixture of these). In the examples: (1) 1 - bromo - 2 - chloro - propane is treated with the sodio-derivative of diphenylacetonitrile to give 2 : 2 - diphenyl - 4 - chloro - valeronitrile, which is separated from traces of the accompanying 2 : 2 - diphenyl - 3 - (bromomethyl)-butyronitrile and converted via 2 : 2-diphenyl - 4 - N - morpholino - valeronitrile into the desired ketone with ethyl magnesium iodide; (2) 1 - N - morpholino - 2 - chloropropane with the sodio-derivative of diphenylacetonitrile gives a mixture of 2 : 2-diphenyl4 - N - morpholino - valeronitrile and 2 : 2-diphenyl - 3 - methyl - 4 - N - morpholino-butyronitrile. The nitriles may be separated via their hydrochlorides, or the crude mixture submitted to the Grignard reaction when the valeronitrile reacts more rapidly than the other to give the desired ketone.
