Palmitoyl chloride → 3'-deoxy-3'-fluoro-5'-O-palmitoyl-thymidine

참여 물질

반응 단계

At 0° C., 1.2 equivalents of palmitoyl chloride are added to a solution of 3'-deoxy-3'-fluorothymidine in pyridine. The solution is warmed slowly to room temperature. As soon as a thin layer chromatographic control (CHCl3 /methanol=95/5 on silica gel) shows a complete reaction, the solution is poured into ice water. The aqueous phase is decanted, the resulting oil is chromatographed on silica gel with chloroform eluent. The title compound is recovered from the suitable fractions by evaporation of the solvent. M.P. 65°-66° C. (cyclohexane).
