Participants

Reaction Steps

The product of Example 19B (150 mg, 0.38 mmol) was treated with trifluroacetic acid (2 mL) according to the procedure of Example 18C. The title compound was purified by chromatography (SiO2, CH2Cl2:MeOH:NH3.H2O, 90:10:1, Rf. 0.07) as solid (30 mg, yield, 26%). 1H NMR (300 MHz, MeOH-d4) δ 1.88-2.22 (m, 3H), 2.31-2.45 (m, 1H), 2.56-2.64 (m, 1H), 3.27-3.51 (m, 5H), 3.84-3.96 (m, 1H), 5.36-5.45 (m, 1H), 6.87 (d, J=8.5 Hz, 2H), 7.42 (d, J=8.5 Hz, 2H), 8.77 (s, 2H) ppm. MS (DCl/NH3) m/z 297 (M+H)+.
