Reaction Conditions

Reaction Steps

To a solution of the product from Example 126, Part A (80 mg, 0.15 mmol) in tetramethylene sulfone (1.5 ml) was added 1H-1,2,3-triazole (10 μL, 0.17 mmol) and potassium carbonate (73 mg, 0.53 mmol). The mixture was heated for 35 min at 130° C. in a microwave reactor. After cooling to room temperature, the mixture was partitioned between 1 N aqueous HCl (10 ml) and EtOAc (2×10 ml). The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by column chromatography on silica gel using 3% MeOH in CH2Cl2 as the eluent to give the title compound (37 mg, 46%). 1H NMR (300 MHz, DMSO-d6) δ 11.41 (d, J=1.84 Hz, 1H) 10.10 (s, 1H) 8.29 (d, J=1.10 Hz, 1H) 8.05 (d, J=16.18 Hz, 1H) 7.95 (d, J=8.82 Hz, 1H) 7.82 (d, J=2.21 Hz, 1H) 7.74 (d, J=8.09 Hz, 1H) 7.51 (d, J=2.57 Hz, 1H) 7.46 (d, J=0.74 Hz, 1H) 7.39 (dd, J=8.64, 2.39 Hz, 1H) 7.20-7.30 (m, 2H) 5.65 (dd, J=7.91, 2.02 Hz, 1H) 3.80 (s, 3H) 3.07 (s, 3H) 1.38 (s, 9H).
