実験手順

Tetrahydro-furan-3-carboxylic acid (81 mg), PyBOP (268 mg) and DIPEA (0.244 ml) are added to a solution of C-{2-methyl-5-[5-(3,4,5-trichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-furan-3-yl}-methylamine (200 mg) in dichloromethane (4 ml). After 24 hours at room temperature, the reaction is quenched with water. The reaction mixture is extracted three times with dichloromethane. The combined organic phases are washed with a saturated solution of NaHCO3 and with a saturated aqueous solution of NaCl, dried over Na2SO4 and concentrated in vacuo. The crude product is purified on a semi-preparative HPLC to yield tetrahydro-furan-3-carboxylic acid {2-methyl-5-[5-(3,4,5-trichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-furan-3-ylmethyl}-amide (189 mg, compound 2.3 in Table 2) as a white foam. MS (HPLC/MS): 525 (MH+). Retention time: 1.97 min.
