HCID 11073869Cyclohexanecarboxylic acid, 4-(hydroxymethyl)-, methyl ester

Procedure

To a cooled (0° C.) solution of 4-(hydroxymethyl)cyclohexanecarboxylic acid (40 g) in methanol (632 mL) was added thionyl chloride (22.15 mL) dropwise via an addition funnel. The reaction was slowly warmed to room temperature, stirred for 1 hour, concentrated by rotary evaporation, and the residue was purified by regular phase flash column chromatography (Analogix, 0-100% hexanes/ethyl acetate).
