실험 절차

To a solution of 10 parts of 3-(cyclohexyloxy)-1-propanol in 160 parts of dichloromethane there were added 11.2 parts of N,N-diethylethanamine and dropwise 8.14 parts of methanesulfonyl chloride. The whole was stirred for 9 hours at room temperature. The reaction mixture was washed with Na2CO3 (aq.) and water and was then dried, filtered and evaporated. The residue was purified by column chromatography (silica gel; CH2Cl2 /CH3OH 99:1). The eluent of the desired fraction was evaporated and the residue was co-evaporated with methylbenzene. The product was filtered off and dried, yielding 8.6 parts (57.8%) of 3-(cyclohexyloxy)-1-propanol methanesulfonate (ester) (interm. 21).
