A solution of the product of Example 12 (350 mg, 0.69 mmol) in THF (25 mL) was treated with lithium aluminum hydride (129 mg, 3.4 mmol) inducing a moderate exotherm. The mixture was allowed to return to room temperature and stirred for 2 h, then briefly warmed to reflux, cooled, and quenched with ethyl acetate (50 mL) followed by saturated ammonium chloride (50 mL). The aqueous layer was extracted with ethyl acetate (2×50 mL), and the combined organic layers were dried (sodium sulfate), concentrated; and purified via radial chromatography (silica gel, 1:1 hexane:ethyl acetate, 5% methanol, under an ammonia atmosphere) to provide 248 mg (64%) of the title compound as a yellow foam: 1H NMR (300 MHz, CDCl3) δ7.28 (d, J=8.5 Hz, 1H), 7.05 (d, J=8.5 Hz, 1H), 6.79 (m, 3H), 6.72 (d, J=2.6 Hz, 1H), 6.65 (d, 9.0 Hz, 2H), 6.58 (d, J=2.6 Hz, 1H), 6.52 (dd, J=8.6, 2.6 Hz, 1H), 4.65 (s, 2H), 3.94 (t, J=6.1 Hz, 2H), 3.74 (s, 3H), 3.74 (s, 3H), 2.96 (dd, J=8.3, 5.6, 2H), 2.81 (dd, J=8.3, 5.9 Hz, 2H), 2.66 (t, J=6.1 Hz, 2H), 2.43 (m, 4H), 1.5-1.6 (m, 4H), 1.3-1.5 (m, 2H); 13C NMR (75 MHz, CDCl3) δ158.5, 158.3, 153.3, 141.7, 138.4, 134.6, 132.3, 126.6, 126.2, 125.3, 122.9, 121.7, 120.5, 114.9, 113.4, 112.3, 111.2, 111.0, 65.8, 57.8, 55.6, 55.2, 55.1, 54.8, 29.0, 25.7, 24.0, 22.2; IR (CHCl3) 1610, 1506 cm-1 ; MS (FD) m/e 496 (M+); Anal. calc'd. for C32H36N2O3 : C, 77.37; H, 7.32; N, 5.64.
