Reaction Conditions

Reaction Steps

To a stirred mixture of 75 parts of 4-(4-methoxyphenyl)cyclohexanol and 1000 parts of pyridine are added dropwise 62 parts of methanesulfonyl chloride (exothermic reaction: temperature rises to 40° C.). Upon completion, the whole is heated to 65° C. and stirring is continued for 2 hours, while meantime the mixture is allowed to cool to room temperature. The reaction mixture is evaporated and 1000 parts of water are added to the residue. The product is extracted with dichloromethane. The extract is washed with water, dried, filtered and evaporated. The residue is crystallized from 2-propanol, yielding 80.5 parts of 4-(4-methoxyphenyl)cyclohexyl methanesulfonate.
