실험 절차

(R)-(2,2-Dimethyl-1,3-dioxolan-4-yl)methyl methanesulfonate was prepared from (S)-(2,2-dimethyl-1,3-dioxolan-4-yl)methanol (Sigma-Aldrich, 99% ee) by a known literature procedure (H. S. Kim, D. Barak, T. K. Harden, J. L. Boyer and K. A. Jacobson, J. Med. Chem., 2001, 44, 3092). The title compound was prepared in the same way as described by M. Lemaire, F. Posada, J.-G. Gourcy and G. Jeminet, Synlett, 1995, 627. A solution of (R)-(2,2-dimethyl-1,3-dioxolan-4-yl)methyl methanesulfonate (3.9 g, 18.55 mmol) and benzylamine (8.10 ml, 74.2 mmol) was refluxed in CH3CN (50 ml) for 48 h. The solvent was evaporated and the residue dissolved in EtOAc and washed with aqueous sat. NaHCO3, dried and the solvent evaporated. The residue was chromatographed (EtOAc-hex, 6:4 then 8:2) to give (S)—N-benzyl-1-(2,2-dimethyl-1,3-dioxolan-4-yl)methanamine (3.1 g, 14.01 mmol, 76% yield) as a yellow oil.
