実験手順

A vial was charged with isoxazol-3-amine (6.09 microliters, 6.93 mg, 0.082 mmol) (from Aldrich Co.), perfluorophenyl 1-(2-chloro-3′-fluoro-5-methoxy-[1,1′-biphenyl]-4-yl)isoquinoline-6-sulfonate (INTERMEDIATE TTTT, 45.67 mg, 0.075 mmol) and THF (0.5 mL) to give a clear solution. The vial was cooled in an ice-water bath for 10 min, then lithium bis(trimethylsilyl)amide (1M in THF) (65.9 μl, 0.065 mmol) was added. After 40 min, additional portions of amine (10 microliters) and LHMDS solution (0.05 mL) were added. LCMS after 10 min showed mainly the desired product. The mixture was purified directly on silica gel (12-g Redi-Sep Gold column, 0-5% MeOH/DCM) to give 1-(2-chloro-3′-fluoro-5-methoxy-[1,1′-biphenyl]-4-yl)-N-(isoxazol-3-yl)isoquinoline-6-sulfonamide (23.72 mg, 0.047 mmol, 62.1% yield) as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ=11.92 (br. s., 1H), 8.78-8.72 (m, 2H), 8.69 (d, J=1.7 Hz, 1H), 8.16 (d, J=5.5 Hz, 1H), 8.01-7.84 (m, 2H), 7.64-7.53 (m, 2H), 7.49-7.40 (m, 2H), 7.37-7.29 (m, 1H), 7.27 (s, 1H), 6.50 (d, J=1.9 Hz, 1H), 3.70 (s, 3H). m/z (ESI) 510.2 (M+H)+.
