2-Ethylsulfonyl-5-hydroxyaniline → 4-(2-Ethylsulfonyl-5-hydroxyanilino)-2-(2-pyrazinyl)-6-trifluoromethylpyrimidine

Participants

Reaction Steps

The title compound was prepared from 4-chloro-2-(2-pyrazinyl)-6-trifluoromethylpyrimidine (40 mg, 0.154 mmol) and 2-ethylsulfonyl-5-hydroxyaniline (46 mg, 0.231 mmol) similar to Example 180. The reaction mixture was evaporated under vacuum to give a residue. The residue was precipitated using acetone to give the product as a yellow solid (30 mg, 46%). 1H NMR (DMSO-d6): 9.45 (s, 1H), 8.71 (m, 3H), 7.84 (brs, 1H), 7.0 (brd, 1H), 6.08 (brd, 1H), 3.0 (q, 2H), 1.0 (t, 3H).
