Reaction Steps
A mixture of 6.5 parts of 2-amino-N-[2-[4-(4-fluorobenzoyl)-1-piperidinyl]ethyl]benzamide, 0.5 parts of paraformaldehyde, 3 drops of sodium hydroxide solution 50%, 80 parts of ethanol and 10 parts of water is stirred and refluxed overnight. The reaction mixture is allowed to cool to room temperature while stirring. The precipitated product is filtered off, washed with ethanol and crystallized from 200 parts of ethanol, yielding 3.3 parts (50%) of 3-[2-[4-(4-fluorobenzoyl)-1-piperidinyl]ethyl]-2,3-dihydro-4(1H)-quinazolinone; mp. 203.4° C.
