Participants

Reaction Steps

To 4-(benzylamino)-2-hydroxybicyclo[2.2.2]octane-1-carboxylic acid ethyl ester (6.0 g, 19.8 mmol), there were added toluene (42.0 g), tetrahydrofuran (10.8 g) and triethylamine (4.0 g, 39.6 mmol) and then the resulting mixture was stirred. Methanesulfonyl chloride (2.9 g, 24.9 mmol) was added dropwise to the mixture, followed by the stirring thereof for one hour and 30 minutes. After quenching the reaction mixture with water, the resulting mixture was subjected to extraction procedures and the organic phase was quantitatively analyzed (according to the LC technique). As a result, the yield of the desired product was found to be 100% (the internal standard substance used was m-xylene).
