Reaction Steps

To a degazed solution of 289 (43 mg, 0.096 mmol) in AcOEt (4 mL) was added PtO2 (3 mg, 0.01 mmol) and the reaction mixture was stirred at room temperature under a 1 atm pressure of H2 for 16 h. The reaction flask was purged with N2 then the reaction mixture was filtered through celite, rinsed with MeOH and concentrated. The crude residue was purified three times by flash chromatography on silica gel (MeOH/DCM: 2/98, AcOEt/DCM: 30/70 and AcOEt/CHCl3: 30/70) to afford the title compound 290 (10 mg, 0.22 mmol, 23% yield). 1H NMR (CDCl3) δ (ppm): 8.10 (s, 1H), 7.91 (d, J=8.0 Hz, 2H), 7.50 (d, J=8.0 Hz, 2H), 7.34 (d, J=7.5 Hz, 1H), 7.10 (t, J=7.5 Hz, 1H), 6.96-6.85 (m, 2H), 6.64 (s, 2H), 5.33 (t, J=7.0 Hz, 1H), 5.21 (t, J=7.0 Hz, 1H), 3.89 (s, 6H), 3.85 (s, 3H), 2.59-2.40 (m, 2H), 2.09-1.88 (m, 2H).
