Reaction Steps

A solution of 0.2 g (0.38 mmol) of the product of Example 63 was dissolved in 5 mL of MeOH and was treated with 1 mL of 1N NaOH (1.0 mmol) and stirred over night. The resulting solution was extracted with EtOAc (3×10 mL). The organic phase was washed with water (2×5 mL) and brine (1×5 mL) and dried over MgSO4. The mixture was filtered and concentrated in vacuo and the residue was purified by flash chromatography over silica gel eluting with 80:19:1 EtOAc: hexane:acetic acid to give 0.17 g (0.36 mmol) of a white foam, 93% yield. 1H-NMR (CD3OD): 0.88 (t, 3H, J=7.38 Hz), 1.41 (m, 2H), 1.48 (m, 2H), 2.73 (3 line m, 2H, J=8.03 Hz), 4.60 (s, 2H), 5.38 (bs, 2H), 7.08 (m, 4 H), 7.20 (m, 1H), 7.50 (m, 2H), 7.61 (m, 2H), 7.77 (dd, 1H, J=2.0, 9.0 Hz), 8.17 (s, 1H). FABMS m/e: 467 (M+ +1) calc. for C27H26N6O2
