Reaction Steps

[3-Fluoro-4-[4-(methylthio)-1H-1,2,3-triazol-1-yl]phenyl] carbamic acid benzyl ester (Intermediate 49) (27.4 g, 76.5 mmol), LiHMDS (1M in THF, 91 ml) and R-(−)-glycidyl butyrate (11.5 g, 79.7 mmol) were reacted following the procedure for Intermediate 25 to give the crude title compound (19.4 g), which was used without further purification.
