Reaction Steps

Title compound was prepared following general procedure 1 starting from Intermediate 13 (120 mg; 0.51 mmol) and Intermediate 1 (90 mg; 0.51 mmol). Reaction mixture was filtered over a SPE-NH2 column, washed with THF followed by evaporation of the solvent under reduced pressure. Purification by silica column chromatography (EtOAc/c-Hex, 30/70 to 100/0) afforded the title compound as a brown powder. 1H NMR (DMSO, d6): δ 12.78 (s, 1H), 8.39-8.37 (m, 2H), 8.31 (s, 1H), 8.24 (dd, J=8.8, 2.2 Hz, 1H), 7.95-7.92 (m, 1H), 7.78-7.75 (m, 1H), 7.32 (d, J=8.8 Hz, 1H), 4.23-4.22 (m, 1H), 3.38-3.35 (m, 2H), 1.82-1.57 (m, 6H), 1.17 (d, 6.6 Hz, 3H). HPLC (Method A) Rt 2.71 min (Purity: 86.6%). LC/MS (method B): 358.3 (M+H)+.
