実験手順

To a solution of 33 (0.206 g, 0.657 mmol, 1.2 eq) and aniline (0.051 g, 0.548 mmol) in dry DMF (5 ml) HATU (0.315 g, 0.9087 mmol, 1.5 eq) and DIPEA (0.340 g, 2.63 mmol, 4 eq) was added at room temperature under Ar. After stirring overnight at room temperature, the reaction mixture was quenched with water (10 mL) and extracted with ethyl acetate (2×15 ml). The organic extracts were collected, dried over Na2SO4 and the solvent was distilled off under reduced pressure. The crude compound was purified by chromatography on silica gel (3:7 ethyl acetate/hexane, v/v, Rf 0.30) to give 34 as a white solid (0.120 g, 0.307 mol, 47%), mp 165-167° C. 1H NMR (400 MHz, CDCl3) δ 1.43 (9H, s), 2.55 (1H, dd, J 5.0, 13.8 Hz), 2.75 (1H, dd, J 8.4, 13.6 Hz), 3.16-3.39 (2H, m), 3.52-3.57 (1H, m), 4.60 (1H, bs), 7.07-7.13 (3H, m), 7.29-7.32 (4H, m), 7.54 (2H, d, J 8.4 Hz), 8.61 (1H, bs).
