Reaction Steps

To a solution comprising 2.3 g of 4-(2-keto-1-benzimidazolinyl)-piperidine, 1.1 g of triethylamine, and 20 ml of chloroform is added 2.2 g of phenacyl bromide, and the reaction is carried out under the same conditions as in Example 1. The same post-treatment as in Example 1 is conducted to obtain 3.2 g of a crude product. Recrystallization of the product from a mixture solution of ethanol and ethyl acetate (2:3 by volume) yields 2.92 g of 1-[2-oxo-2-phenyl-1-ethyl]-4-(2-keto-1-benzimidazolinyl)-piperidine.
