実験手順

To a solution of 2,6-dimethylbenzoic acid (0.100 g; 0.668 mmol) in DMF (5 ml) and DIPEA (0.12 ml) was added {[amino(phenyl)methyl]cyclopentyl}methylamine D31 enantiomer 2 (0.124 g; 0.608 mmol) and HATU (0.254 g; 0.668 mmol). The resulting mixture was allowed to stir at room temperature for 3 days and then the DMF was evaporated off under reduced pressure. Residual material was partitioned between ethyl acetate and water, washed with water and the organic layer was dried (Na2SO4) and evaporated. The residual material was dissolved in DCM (2 ml) and loaded onto an SCX cartridge. Washing with DCM, then methanol followed by elution with 1 M ammonia in methanol afforded the title product (155 mg; 76%). 1H NMR (CDCl3) δ: 1.3-1.8 (9H, m), 2.21 (3H, s), 2.28 (6H, s), 5.07 (1H, m), 7.0 (2H, m), 7.1-7.4 (7H, m). Mass Spectrum (Electrospray LC/MS). Found 337 (MH+). C22H28N2O requires 336. Ret. time: 1.86 min.
