Reaction Steps

A solution of 0.24 (0.4 mmol) (2S,4R)-2-Chloro-4-[2-(2,4,5-trifluoro-benzyloxymethyl)-4-tritylsulfanyl-pyrrolidin-1-yl]-pyrimidine in 1 ml MeOH was treated at 0° C. with 0.16 ml (0.88 mmol) sodium methylate (5.5 M in MeOH) and kept at this temperature (2 h), warmed up and heated for 10 h at 75° C. After evaporation and extraction with aqueous saturated NH4Cl/Et2O (3×), the organic phases were washed with aq. 10% NaCl, dried (Na2SO4) and evaporated to give 0.19 g (77%) 2-Methoxy-4-[(2S,4R)-2-(2,4,5-trifluoro-benzyloxymethyl)-4-tritylsulfanyl-pyrrolidin-1-yl]-pyrimidine, MS: 628 (MH+), which was deprotected (see General method for S-deprotection, Method D) to give (3R,5S)-1-(2-Methoxy-pyrimidin-4-yl)-5-(2,4,5-trifluoro-benzyloxymethyl)-pyrrolidine-3-thiol, MS: 386 (MH+).
