실험 절차

Prepared using General Procedure 10: A stirred solution of (S)-tert-butyl 2-(((benzyloxy)carbonyl)amino)-3-(4-(5-bromopyrimidin-2-yl)phenyl)propanoate INT-7 (759 mg, 1.48 mmol), (4-(heptyloxy)phenyl)boronic acid (455 mg, 1.93 mmol) and sodium bicarbonate (311 mg, 3.70 mmol) in acetonitrile (5 ml), THF (5 ml), and water (4 ml) was degassed with N2 for 5 min. Pd(dppf)Cl2 (108 mg, 0.15 mmol) was added and the reaction was heated to 110° C. in the microwave for 50 min. The reaction was diluted with EA and water then filtered. The organic phase was dried over MgSO4, filtered, and concentrated. The crude product was purified by chromatography on silica gel (EA/hexanes) to afford 591 mg (62%) of (S)-tert-butyl 2-(((benzyloxy)carbonyl)amino)-3-(4-(5-(4-(heptyloxy)phenyl)pyrimidin-2-yl)phenyl)propanoate INT-8 as a yellow solid. LCMS-ESI (m/z) calculated for C38H45N3O5: 623.8; no m/z observed, tR=3.42 min (Method 8).
