Procedure: From 9.3 g. of ethyl 2-methyl-5-oxo-1-pyrrolidineacetate and 10.7 g. of 2-(1-piperidinyl)propylamine (J. Chem. Soc. 1947, 1511), following the procedure of Example 9, there is obtained (±)-2-methyl-5-oxo-N-[2-(1-piperidinyl)propyl]-1-pyrrolidineacetamide; m.p. 111°-112° C. after recrystallization from heptane.

Procedure: To a solution of 4.00 g of 3-methylflavone-8-carboxylic acid and 1.98 ml of triethylamine in 74 ml of anhydrous tetrahydrofuran was added a solution of 1.50 ml of ethyl chlorocarbonate in 15 ml of anhydrous tetrahydrofuran under ice-cooling and the mixture was stirred for 1 hour. To the mixture, a solution of 2.03 g of 2-piperidinopropylamine in 20 ml of anhydrous tetrahydrofuran was added and the mixture was stirred for 1.5 hours under ice-cooling and further at room temperature for 16 hours. The reaction mixture was treated by the same procedure as in Examples 3(b) to give 4.15 g of colorless crystals, which were recrystallized from ethyl acetate as colorless needles, m.p. 106.5°-108.5° C. cooling the mixture was stirred for 1.5 hours under ice- The reaction mixture was treated by the same procedure as in Examples 3(b)
