実験手順

A solution of (S)-2-[4-(2-chloro-6-fluoro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-3-cyclohexyl-propionic acid (prepared as in Example 67, 206 mg, 0.54 mmol) in dichloromethane (5 mL) was treated with 6-amino-nicotinic acid methyl ester (110 mg, 0.72 mmol), bromotripyrrolidinophosphonium hexafluorophosphate (503 mg, 1.1 mmol) and N,N-diisopropylethylamine (150 mg, 1.1 mmol). The reaction mixture was stirred for 4 h at 25° C., under nitrogen. The reaction mixture was diluted with ethyl acetate, washed with saturated ammonium chloride, water, a saturated sodium chloride solution and dried over sodium sulfate. The organic layer was concentrated, and the crude product was purified by ISCO flash chromatography (Teledyne Isco RediSep Flash Column 12 g, 0% to 100% ethyl acetate/hexanes) to afford 6-{(S)-2-[4-(2-chloro-6-fluoro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-3-cyclohexyl-propionylamino}-nicotinic acid methyl ester (90 mg, 33%): 1H NMR (300 MHz, DMSO-d6) δ ppm 0.77-1.36 (m, 6H) 1.40-1.92 (m, 7H) 3.86 (s, 3H) 4.29 (d, J=18.7 Hz, 1H) 4.64 (d, J=18.7 Hz, 1H) 5.00 (s, 1H) 5.01-5.10 (m, 1H) 7.30-7.61 (m, 3H) 8.16 (d, J=8.8 Hz, 1H) 8.29 (dd, J=8.8, 2.1 Hz, 1H) 8.87 (d, J=2.1 Hz, 1H) 11.32 (s, 1H). HR-ES-MS m/z calculated for C26H27ClFN3O5 [M+H]+ 516.1696, observed 516.1696.
