Removal of the Boc and silyl protecting groups of (XLI) was accomplished by treatment with trifluoroacetic acid in chloroform to provide, after chromatographic separation, the 3-alpha-polyamino sterol (XLII). Subsequent catalytic hydrogenation removed the benzyl protecting group of (XLVII), yielding (XLIII). Finally, sulfation of alcohol (XLIII) with sulfur trioxide-pyridine gave rise to the title compound.
