Abstract: The present invention relates to a method for making a compound of the structure: ##STR1## comprising the steps: (a) adding 6-deoxy-.alpha.-L-mannopyranosyl bromide, 2,3,4-tri-O-benzoate; DMSO; a base, selected from the group including tertiary amines, amidines, bicarbonates, carbonates, heteroaryl amine, and a solvent, hydrocarbons, esters, and ethers, in a slurry heated to 50.degree.-150.degree. C.;(b) stirring the reaction mixture at 50.degree.-150.degree. C. for 5 minutes to 30 minutes,(c) pouring the reaction mixture over ice water; and(d) extracting the product with a solvent selected from the group consisting of chlorinated solvents, aromatic hydrocarbons, esters, ethers, and evaporating said layer to give a solid.

Abstract: Disclosed are 14-aminosteroid compounds, including pharmaceutically acceptable acid salts and esters thereof, useful in treating individuals afflicted with congestive heart failure, which compounds have the general formula: ##STR1## wherein R.sub.3 is a deoxy or oxygen-substituted monosaccharide sugar residue and R.sub.1, R.sub.2 and R.sub.4 are various other substituents as defined herein.
