Participants

Reaction Steps

Thionyl chloride 5 ml was added to 4-[2-(5-hydroxy-2-adamantyl)-ethyl]-4-azatricyclo[4.3.1.1 3.8 ] undecane 105 mg obtained in example 8 and refluxed for 4 hours. Reaction mixture was concentrated in vacuo and saturated sodium bicarbonate was added to the residue to set to alkaline pH, then extracted with chloroform. The extract was dried by adding ahnydrous sodium sulfate. After removal of drying agent, the filtrate was concentrated in vacuo, and the residue was purified by means of silica gel column chromatography (Wako gel, C200, chloroform: methanol=50:1-20:1) to obtain the product as a mixture of stereoisomer. (a mixture of stereoisomer 1:1 measured by gas chromatography)
