Reaction Steps

To a solution of 4-(cyclopropoxy)-3-[(6-hydroxy-1,4-oxazepan-4-yl)sulfonyl]benzoic acid (170.00 mg, 475.68 umol, 1.00 eq) and 3-chloro-4-fluoro-aniline (69.24 mg, 475.68 umol, 1.00 eq) in DMF (5.00 mL) were added HATU (180.87 mg, 475.68 umol, 1.00 eq) and DIPEA (122.95 mg, 951.36 umol, 2.00 eq). The mixture was stirred at 25° C. for 16 hr. TLC detected the reaction was complete, the mixture was poured into water, extracted with EA, the combined organic layer was dried over anhydrous Na2SO4, concentrated, the residue was purified by prep-HPLC (FA) to afford product N-(3-chloro-4-fluoro-phenyl)-4-(cyclopropoxy)-3-[(6-hydroxy-1,4-oxazepan-4-yl)sulfonyl]benzamide (94.10 mg, 194.05 umol, 40.79% yield) as white solid. 1H NMR (400 MHz, MeOD) δ 8.48 (d, J=2.01 Hz, 1H), 8.23 (dd, J=8.66, 2.13 Hz, 1H), 7.96 (dd, J=6.78, 2.51 Hz, 1H), 7.70 (d, J=8.78 Hz, 1H), 7.59-7.65 (m, 1H), 7.27 (t, J=8.91 Hz, 1H), 4.07-4.13 (m, 1H), 4.03 (t, J=6.53 Hz, 1H), 3.77-3.97 (m, 4H), 3.61-3.73 (m, 2H), 3.21-3.30 (m, 1H), 3.11 (dd, J=14.56, 7.53 Hz, 1H), 0.84-1.04 (m, 4H).
