该中间体在本合成路线中的序号：(L)The primary hydroxyl group of diol (XLVIII) was selectively mesylated with methanesulfonyl chloride and collidine at low temperature. The resultant mesylate (IL) was then condensed with tetrabutylammonium azide in hot DMF to produce the alkyl azide (L). The azide function of (L) was finally reduced to the corresponding primary amine by treatment with trimethylphosphine in moist THF.
