Procedure

The title compound was prepared by mixing the product of Example 38B with 1:1 mixture of TFA and dichloromethane. After 2 hours, the solvent was removed under reduced pressure, the residue was basified with saturated sodium bicarbonate and extracted three times with dichloromethane. The combined organic layers were washed with brine, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The resulting residue was purified by column chromatography (0.5% ammonium hydroxide and 5% methanol in dichloromethane) to provide the title compound. 1H NMR (500 MHz, CDCl3) δ ppm 9.19-9.26 (s, 1H) 9.01 (s, 2H) 8.09 (d, J=8.54 Hz, 1H) 8.05 (d, J=1.53 Hz, 1H) 7.65 (dd, J=8.54, 1.83 Hz, 1H) 3.81-3.92 (m, 1H) 3.60-3.71 (m, 1H) 3.03-3.12 (m, 1H) 2.95-3.03 (m, 1H) 2.87-2.95 (m, 1H) 2.72-2.79 (m, 1H) 2.64-2.71 (m, 2H) 2.50-2.62 (m, 3H) 2.32-2.46 (m, 3H) 1.91-2.00 (m, 1H) 1.57-1.67 (m, 1H).
