Participants

Reaction Steps

The product from Example 1, Part C (200 mg, 0.6 mmol) and 2-aminopyrazine (89 mg, 0.9 mmol) were reacted as described in Example 5. After evaporation of the reaction solvent the residue was partitioned between water and EtOAc, and the organic phase was washed with EtOAc. The combined organics were washed with brine, dried (Na2SO4), filtered, and evaporated. The title compound was obtained as a tan solid by silica gel chromatography. 1H NMR (400 MHz, CDCl3) δ 9.48 (s, 1H), 8.70 (br s, 1H), 8.36 (d, J=2 Hz, 1H), 8.20 (m, 1H), 7.22 (d, J=8 Hz, 2H), 6.83 (d, J=8 Hz, 2H), 5.14 (d, J=14 Hz, 1H), 4.63 (s, 1H), 4.16 (d, J=14 Hz, 1H), 3.77 (s, 3H), 3.04 (d, J=16 Hz, 1H), 2.97 (d, J=16 Hz, 1H), 1.95 (s, 3H), 1.84 (s, 3H).
