Reaction Steps
To a solution of the product of Example 13 in 100 mL of methanol, cooled to 0° C., was added 2.69 g (0.071 mol) of solid sodium borohydride in portions over 15 minutes. The reaction was then concentrated in vacuo, acidified with 10% HCl solution and extracted with methylene chloride. The combined organic layers were washed with water and brine, dried over MgSO4, filtered and concentrated in vacuo. The resulting crude thiol was dissolved in 50 mL of trifluoroacetic acid and 5.98 g (0.023 mol) of trityl alcohol was added. After stirring at room temperature for 1 h the reaction mixture was concentrated in vacuo and the residue was chromatographed on silica gel eluting with ethyl acetate/hexanes (1:50) to provide 5.26 g (61%) of the desired product as a colorless oil. CI Mass Spec: 473.5 (M+H).
