Participants

Reaction Steps

2-(methylsulfonyl)acetic acid (22 mg, 0.16 mmol) was added to 3-fluoro-3-(4-(5-(3,4,5-trichlorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)phenyl)cyclobutanamine (Preparation 16, 50.0 mg, 0.10 mmol) in DMF (1.5 mL) along with DIPEA (54 μL, 0.31 mmol) and HATU (61 mg, 0.16 mmol). The mixture is stirred for 3 days at room temperature. The reaction mixture is partitioned between brine (5 mL) and EtOAc (5 mL). The organics are separated, dried over MgSO4, filtered and evaporated to give a residue, which is purified on regular silica eluting from neat DCM to 15% MeOH/DCM to give the title compound (20 mg): 1H NMR (DMSO-d6) δ: 8.83 (1H, d), 7.85 (2H, s), 7.79 (2H, d), 7.58 (2H, d), 4.60-4.51 (1H, m), 4.42-4.30 (2H, m), 4.04 (2H, s), 3.12 (3H, s), 2.96-2.86 (2H, m), 2.65-2.54 (2H, m); m/z (Cl) 602.
