Participants

Reaction Steps

A solution of the product from Example 1B (48.5 mg, 0.197 mmol) and the product from Example 210A (0.0384 g, 0.202 mmol) in 1,2-dichloroethane (0.6 mL) and 1-methyl-2-pyrrolidinone (0.20 mL) was microwaved at 180° C. for 20 minutes, diluted with EtOAc, washed with sat NaHCO3 and brine, dried (Na2SO4), filtered, and chromatographed (12% EtOAc/DCM) to give 31.2 mg of the title compound as a tan solid: 1H NMR (300 MHz, DMSO-d6) δ 11.11 (s, 1H), 8.34-8.27 (m, 1H), 8.06-7.93 (m, 2H), 7.93-7.84 (m, 1H), 3.85-3.78 (m, 4H), 3.12-3.04 (m, 4H), 2.44 (s, 2H), 2.33 (t, J=6.6, 1H), 2.17 (s, 2H), 1.83-1.46 (m, 10H); MS (ESI+) M/Z 409 (M+H)+.
