실험 절차

A mixture of 3.1 parts of acetic acid anhydride, 5 parts of 1-[2-[4-[2-(4-fluorophenyl)-2-oxoethyl]-1-piperidinyl]ethyl]-1,3-dihydro-2H-benzimidazol-2-one and 56 parts of methylbenzene is stirred and refluxed for 4 hours. The reaction mixture is cooled and water and ammonium hydroxide are added. Upon stirring, the product is crystallized. It is filtered off, washed with water and dried in vacuo, yielding 2.2 parts (40%) of 1-acetyl-3-[2-[4-[2-(4-fluorophenyl)-2-oxoethyl]-1-piperidinyl]ethyl]-1,3-dihydro-2H-benzimidazol-2-one; mp. 149.2° C.
