실험 절차

To title compound of Step D (0.106 g, 0.296 mmol), 2-trifluoromethylphenylboronic acid (0.084 g, 0.444 mmol), K3PO4 (0.189 g, 0.888 mmol), Pd(dba)2 (0.007 g, 0.012 mmol) and QPhos (0.004 g, 0.006 mmol) was added PhCH3 (3 mL) and the reaction was heated to 80° C. for 18 h. The reaction was cooled to rt, diluted with EtOAc, filtered through a small silica plug and concentrated. Silica gel chromatography (0-30% EtOAc in hexanes) gave 0.062 g (49%) of the title compound. MS (ESI): mass calcd. for C22H24F3NO4, 423.17. m/z found, 368.1 [M-56]+, 446.2 [M+Na]+. 1H NMR (CDCl3): 7.73 (d, J=7.8 Hz, 1H), 7.55 (t, J=7.3 Hz, 1H), 7.46 (t, J=7.6 Hz, 1H), 7.32 (d, J=7.6 Hz, 1H), 6.93 (s, 2H), 6.56 (s, 1H), 4.92-4.83 (m, 1H), 4.26 (dd, J=10.5, 6.5 Hz, 2H), 4.10 (dd, J=10.5, 4.3 Hz, 2H), 3.93 (s, 3H), 1.43 (s, 9H).
