Solid part was added to xylenes (3 L) and refluxed for 1 hr. H2O (15 ml) was distilled from the reaction mixture by using a Dean-Stark receiver and the reaction mixture was filtered at 80 0C. Washing of solid part with xylenes (3 L) was repeated. Solid part after extraction with xylenes were added to ethanol (8 liters) and refluxed for 1 hour. The reaction mixture was filtrated at 700C and solid part was added to ethanol (4 L) and refluxed for 1 hr. The reaction mixture was filtrated at 70 0C and solid part was extracted with ethanol (4 L) using the same procedure as is it was described above. Ethanol solutions were combined, evaporated from solvent and dried in vacuum at 80 0C to give the acids as their sodium salts (330 g), which, was acidified with a 2 % solution of HCl (2.3 L) and filtered.

In a 1 dram vial with rubber septum and stirbar were combined methyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-((2-(1,1-dioxidothiomorpholino)ethyl)amino)-1-(1-hydroxypropan-2-yl)-5a,5b,8,8,11a-pentamethyl-2,3,3a,4,5,5a,5b,6,7,7a,8,11,11a,11b,12,13,13a,13b-octadecahydro-1H-cyclopenta[a]chrysen-9-yl)benzoate Isomer 1 (0.025 g, 0.035 mmol) and <strong>[38222-83-2]2,6-di-tert-butyl-4-methylpyridine</strong> (0.021 g, 0.104 mmol) in dry chloroform (1 mL). To the stirred solution was added dropwise trifluoromethanesulfonic anhydride (0.013 g, 0.045 mmol) at rt. The mixture was stirred at rt for 1 h, then to the mixture was added morpholine (0.030 mL, 0.346 mmol) and the resulting solution was stirred at rt for 30 min and was then heated to 60 degrees C. for 90 min. The reaction mixture was concentrated under nitrogen stream and redissolved in a minimum quantity of a mixture of THF and MeOH. Purification by reverse phase preparative HPLC (Prep HPLC Method 3) gave the desired product as a white powder (0.0199 g, 50.7percent yield) TFA salt. LCMS: m/z=792.7 (M+H)+, 1.97 min (method 5).
