실험 절차

To a solution of 4-hydroxy-3-nitrobenzoic acid (285 mg, 1.556 mmol) and DMF (5 mL), were added DIPEA (0.69 mL, 3.96 mmol) and HATU (612 mg, 1.611 mmol). After stirring for 45 min, (S)-(3-fluoropyridin-2-yl)(4-(trifluoromethyl)phenyl)methanamine hydrochloride (380 mg, 1.239 mmol, Intermediate 2) was added in one portion. The reaction was stirred at room temperature for 5 h and was then diluted with water (50 mL). The aqueous solution was extracted with EtOAc (3×20 mL). The combined EtOAc layers were concentrated in vacuo and adsorbed onto a plug of silica gel and chromatographed through a Redi-Sep® pre-packed silica gel column (12 g), eluting with 0 to 75% EtOAc in hexane, to provide the title compound as a yellow solid. MS (ESI pos. ion) m/z: 436.1 (M+H).
