実験手順
In 12 ml of acetone was dissolved 887 mg of 2-methyl-1,2,3,4-tetrahydro-3-isoquinolinemethanol, and 932 mg of methyl p-toluenesulfonate was added dropwise to the resulting solution. The mixture was stirred at room temperature for 3 hours to precipitate crystals. The crystals were collected by filtration, washed with acetone and dried under reduced pressure to give 1.31 g of the desired compound.
