실험 절차

A Kimble vial was charged with (1R,2S)-1-[(5-bromo-6-methoxypyrazin-2-yl)amino]-2,3-dihydro-1H-inden-2-ol (0.55 g, 1.63 mmol), Pd2(dba)3 (33 mg, 35 μmol), dicyclohexyl[2-(9-phenanthryl)phenyl]phosphine (64 mg), 2,4-dichlorophenylboronic acid (567 mg, 2.67 mmol), K3PO4 (1.13 g, 5.34 mmol) and toluene (15 mL). The vial was flushed with N2, sealed and heated at 110° C. for 6 hr. Cool to rt, add additional Pd2(dba)3 (33 mg) and 2,4-dichlorophenylboronic acid (0.5 g, 2.7 mmol). Continue heating overnight. Add additional Pd2(dba)3 (33 mg) and 2,4-dichlorophenylboronic acid (0.5 g, 2.7 mmol) and continue heating for 5 hr. Add additional Pd2(dba)3 (33 mg) and 2,4-dichlorophenylboronic acid (0.5 g, 2.7 mmol) and continue heating overnight. The reaction was cooled to rt, diluted with CH2Cl2, washed with sat. aq NaHCO3 and sat. aq. NaCl. Dry organic extract over MgSO4, filter and concentrate. Purify by biotage MPLC (90 g column, 30% ethyl acetate/hexanes) to afford 0.2 g (31%) of (1R,2S)-1-{[5-(2,4-dichlorophenyl)-6-methoxypyrazin-2-yl]amino}-2,3-dihydro-1H-inden-2-ol as an oil: 1H NMR (CDCl3) δ 3.06–3.10, 3.26–3.32, 3.92, 4.79, 5.33, 5.49–5.50, 7.28–7.41, 7.50, 7.74; MS (ESI+) for C20H17Cl2N3O2 m/z 402 (M+H)+.
