Procedure

4-Aminopyrimidine (0.099 g, 1.038 mmol) was dissolved in dimethyl sulfoxide (1.997 ml), and perfluorophenyl 1-(3′-chloro-5′-fluoro-4-methoxy-[1,1′-biphenyl]-3-yl)-2-oxo-1,2-dihydroquinoline-6-sulfonate (0.500 g, 0.799 mmol) in tetrahydrofuran (5.99 ml) was added as a solution. The reaction was cooled to 0° C. and LHMDS, 1.0M in THF (1.837 ml, 1.837 mmol) was added drop wise. The reaction mixture was diluted with EtOAc and 1N HCl (aq). The layers were separated, and the aqueous was washed (xl) with EtOAc. The combined organics were dried over magnesium sulfate, filtered and concentrated in vacuo. The crude material was purified via MPLC, eluting with 0-100% ethyl acetate in heptane (with a 10% DCM additive), to yield 1-(3′-chloro-5′-fluoro-4-methoxy-[1,1′-biphenyl]-3-yl)-2-oxo-N-(pyrimidin-4-yl)-1,2-dihydroquinoline-6-sulfonamide (0.210 g, 0.391 mmol, 49.0% yield) as a white solid. m/z (ESI) 537.0 (M+H)+. 1H NMR (400 MHz, DMSO-d6) δ ppm 3.73 (s, 3 H) 6.75 (d, J=8.91 Hz, 1 H) 6.80 (d, J=9.64 Hz, 1 H) 7.00 (br. s., 1 H) 7.34-7.42 (m, 2 H) 7.59-7.64 (m, 1 H) 7.68 (t, J=1.61 Hz, 1 H) 7.86 (d, J=2.49 Hz, 1 H) 7.89 (dd, J=8.97, 2.02 Hz, 1 H) 8.02 (dd, J=8.76, 2.44 Hz, 1 H) 8.24 (d, J=9.54 Hz, 1 H) 8.27-8.34 (m, 1 H) 8.43 (s, 1 H) 8.60 (s, 1 H). 1-(3′-chloro-5′-fluoro-4-methoxy-[1,1′-biphenyl]-3-yl)-2-oxo-N-(pyrimidin-4-yl)-1,2-dihydroquinoline-6-sulfonamide was separated by chiral SFC on a Chiralpak AD with 30% isopropanol to give (P)-1-(3′-chloro-5′-fluoro-4-methoxy-3-biphenylyl)-2-oxo-N-4-pyrimidinyl-1,2-dihydro-6-quinolinesulfonamide as peak 1 and (M)-1-(3′-chloro-5′-fluoro-4-methoxy-3-biphenylyl)-2-oxo-N-4-pyrimidinyl-1,2-dihydro-6-quinolinesulfonamide as peak 2.

The sulfonamide —NH was not observed in the NMR spectra of the three compounds.
