実験手順

In an atmosphere of nitrogen, 6-chloro-3-hydroxy-hexanoic acid methyl ester (2); 66.5 g {(GC purity; 79.1%, pure amount; 52.6 g (0.295 mol)}, triethylamine (44.7 g, 0.443 mol) and toluene (250 ml) were added to a 500 ml capacity flask, followed by cooling to 5° C. Methanesulfonyl chloride (37.0 g, 0.325 mol) was added dropwise thereto, followed by stirring at 5° C. for 0.5 hour to obtain a toluene solution of 6-chloro-3-methanesulfonyloxy-hexanoic acid methyl ester (3).
