62.5% | With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In DMF (N,N-dimethyl-formamide); dichloromethane; at 0 - 20℃; | To a solution of 3-Methyl-isoxazole-4-carboxylic acid (0.52 g, 4.06 mmol) in DCM (15 mL) and DMF (2 mL), was added HOBt (1.1 g, 8.14 mmol) and EDCI (0.896 g 4.67 mmol). The clear yellow solution was cooled to 0 C and allowed to stir under Ar for 15 minutes. To the solution was added (R)-1-Amino-1,2,3,4-tetrahydronaphthalene (0.73 mL, 5.04 mmol and the reaction mixture was allowed to slowly warm to ambient temperature and was stirred for overnight. Dilution with DCM (50 mL) was followed by aqueous extraction (NaHCO3 water, brine (50 mL), drying over MgSO4, filtration and removal of solvent in vacuo. Silica gel chromatography (0-25% Hexane:EtOAc) afforded the title compound (650 mg; 62.5%) as a sticky solid. 1H NMR (CDCl3) δ 1.88 (m, 3H), 2.12 (m, 1H), 2.51 (s, 3H), 2.81 (m, 2H), 5.32 (m, 1H), 5.99 (bd, 1H), 7.13 (m, 1H), 7.20 (m, 2H) 7.20 (m, 2H); 13C NMR (CDCl3) δ 11.22, 20.15, 29.41, 30.35, 47.93, 116.73, 126.72, 127.88, 128.88, 129.65, 136.25, 138.00, 158.45, 160.28.
