Participants

Reaction Steps

To a solution of 112 (560 mg, 0.923 mmol) in DCM (10 mL) was added 4.0M HCl in dioxane (0.923 mL, 3.69 mmol) and the reaction mixture was stirred at RT for 2 hours. The mixture was diluted with saturated NaHCO3 solution and the layers were separated. The organic phase was collected, dried over anhydrous Na2SO4, filtered and concentrated. The resultant solid was triturated with Et2O to afford title compound 113 (350 mg, 75% yield) as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 8.69 (s, 1H), 8.48 (d, J=5.48 Hz, 1H), 8.00 (s, 1H), 7.82 (d, J=8.41 Hz, 1H), 7.70 (m, 1H), 7.44 (d, J=8.22 Hz, 1H), 7.36 (t, J=9.19 Hz, 1H), 7.19 (m, 1H), 6.56 (m, 2H), 3.75 (s, 2H), 3.39 (t, J=5.67 Hz, 2H), 3.22 (s, 3H), 2.64 (t, J=5.67 Hz, 2H), 2.53 (m, 1H), 0.63 (m, 2H), 0.41 (m, 2H). MS (m/z)=507.5 (M+H).
