Abstract

1,161,688. Production of 1,2-diaryl-3,5- dioxo-4-(31-oxobutyl) pyrazolidine. SPOFA UNITED PHARMACEUTICAL WORKS. 8 Nov., 1966 [12 Nov., 1965], No. 49878/66. Heading C2C. 1,2 - Diaryl - 3,5 - dioxo - 4 - (3<SP>1</SP> - oxobutyl) pyrazolidines are prepared by condensing methyl-#-haloethyl ketones, CH 3 COCH 2 CH 2 X, where X represents halogen, with a 1,2-diaryl- 3,5-dioxo pyrazolidines or salts thereof in the presence of an alkaline condensation agents and acidifying the alkali-metal salts produced. Reference has been directed by the Comptroller to Specification 781,439.
