Procedure

To a solution of (S)-2-(2-amino-5-chlorophenyl)-N-(1,2,3,4-tetrahydronaphthalen-1-yl)isonicotinamide 237b (1.02 g, 2.7 mmol), 3-(2,2-dimethyl-4-oxo-3,7,10,13,16-pentaoxanonadecan-19-yl)benzoic acid 251c (1.19 g, 2.7 mmol), DIPEA (1.04 g, 8.1 mmol) and DMAP (190 mg, 1.55 mmol) in DMF (20 ml) was added HATU (1.13 g, 2.97 mmol). The reaction mixture was heated at 65° C. for 24 hours, then cooled and concentrated. The residue was combined with another run (0.28 mmol scale), dissolved in DCM (150 mL), washed with water (4×50 mL), dried (Na2SO4) and concentrated to dryness. Purification by flash chromatography on silica gel (10% to 30% EtOAc in DCM) gave the title compound (1.44 g).
