To a solution of (S)-2-(4-(tert-butyl)benzamido)-3-(4-(5-(4-(heptyloxy)phenyl)pyrimidin-2-yl)phenyl)propanoic acid Compound 85 (78.0 mg, 0.13 mmol), methanesulfonamide (20.0 mg, 0.21 mmol), and DMAP (16.1 mg, 0.13 mmol) in DMF (1.5 mL) was added EDC (40.3 mg, 0.21 mmol) and the solution stirred overnight at RT. The reaction mixture was diluted in EA (50 mL), washed with aqueous saturated sodium bicarbonate (2×20 mL) and brine (20 mL). The organic layer was dried over MgSO4, filtered, and the solvent removed under reduced pressure. The crude product was purified by chromatography (hexane/EA) to afford 36 mg (40%) of (S)-4-(tert-butyl)-N-(3-(4-(5-(4-(heptyloxy)phenyl)pyrimidin-2-yl)phenyl)-1-(methylsulfonamido)-1-oxopropan-2-yl)benz amide, Compound 299 as a colorless solid. LCMS-ESI (m/z) calculated for C38H46N4O5S: 670.3; found 671.3 [M+H]+, tR=11.01 min (Method 10).
