Reaction Steps
To a solution of (-)-N-t-butyl-4,4-diphenyl-2-cyclopentenylamine (3.54 g) in ethyl acetate (20 ml) was added a solution of methanesulfonic acid (1.16 g) in ethyl acetate (1 ml). The solvent was evaporated in vacuo and diethyl ether was added. After kept standing for 4 hours, the resulting precipitate was collected by filtration to give (-)-N-t-butyl-4,4-diphenyl-2-cyclopentenylamine methanesulfonate (3.90 g).
