実験手順

Alternately, the title compound is prepared as follows: To a solution of 1.6 g. of compound (III) (R1 =C2H5, R=phenyl, X=Cl) (product of 1(c) in 50 ml. of methylene chloride is added 1 ml. of triethylamine and 710 mg. of N-acetylpiperazine. After heating for 2 hours, the solvent is washed with 50 ml. of 1N HCl solution and then with water. The methylene chloride solution is dried and evaporated to dryness, yielding 2.1 g. of compound (I) ##STR14##
