Procedure

A mixture of 3.6 parts of 1-(3-chloropropyl)-2,4(1H,3H)-quinazolinedione, 3.02 parts of (4-fluorophenyl)(4-piperidinyl)methanone hydrochloride, 3.7 parts of sodium carbonate, 0.1 parts of potassium iodide and 120 parts of 4-methyl-2-pentanone is stirred and refluxed overnight using a water-separator. The reaction mixture is cooled, water is added and the layers are separated. The organic phase is dried, filtered and concentrated to a small volume. After cooling the concentrate, the precipitated product is filtered off and crystallized from 2-propanol, yielding 1.3 parts (18.5%) of 1-[3-[4-(4-fluorobenzoyl)-1-piperidinyl]propyl]-2,4(1H,3H)-quinazolinedione; mp. 192.9° C.
