摘要:C7, C10 di-CBZ 10-deacetyl baccatin III of the formula: ##STR1## provides an intermediate for the production of docetaxel. A method of producing this C7, C10 di-CBZ 10-deacetyl Baccatin III is provided. Here, 10-deacetyl Baccatin III is acylated with at least 1.5 equivalents of n-butyl lithium and at least 1.5 equivalents of benzyl chloroformate in tetrahydrofuran. The 10-deacetyl Baccatin III may first be dissolved in tetrahydrofuran after which the n-butyl lithium is added followed by the addition of the benzyl chloroformate. The reaction is preferably at a reduced temperature of less than -20° C. The resulting solution may be quenched with ammonium chloride and reduced to residue. The residue may then be redissolved in an organic solvent, washed, dried and recrystallized to purify the compound.
