Beschreibung
Zusammenfassung:	1,208,230. Pregnane 21 - carbonates. ROUSSEL-UCLAF. 22 April, 1969 [22 April, 1968], No. 20400/69. Headings C2C and C2U. Novel compounds of formula (wherein A is H or OH and n is 0-10) are prepared by condensing the corresponding 21- ols with a compound of formula #11 - Ethoxy - #1 - ethoxy - # - ethoxyethyl chloroformate is prepared by reacting carbonyl chloride with triethyleneglycol monoethyl ether. Antiinflammatory compositions for topical, parenteral and rectal administration comprise a compound of Formula I and a suitable vehicle.
