Procedure

The product of Example 441E (240 mg., 0.32 mmol) in CH2Cl2 (1.6 ml.) was reacted with TFA (1.6 ml.) at room temperature for 30 min. The reaction was concentrated, redissolved in water (4 mL) and treated with solid NaHCO3 (270 mg., 3.2 mmol) with stirring. The solution was purified on a C-18 column eluted with a gradient of methanol in water (0-100%). to give the title compound (202 mg., 92%). 1H NMR (300 MHz, DMSO-D6) δ ppm 1.17-1.40 (m, 12 H) 2.98-3.11 (m, 1 H) 3.66 (s, 3 H) 6.65 (s, 1 H) 7.18-7.27 (m, 1 H) 7.32 (d, J=8.09 Hz, 2 H) 7.48 (d, J=8.09 Hz, 2 H) 7.51-7.62 (m, 1 H) 7.94 (s, 1 H) 8.18-8.29 (s, 1 H) 8.77 (s, 1 H) 9.84 (s, 1 H)
