Reaction Steps

60% Sodium hydride (12 mg, 0.3 mmol) is added to a stirred solution of 3-pentanol (88 mg, 1 mmol) in THF (1 mL). After 0.5 hours [4-(5-bromo-6-ethyl-3-methoxypyrazin-2yl)-3-methoxyphenoxy]trifluoromethane (41 mg, 0.1 mmol) is added. The mixture is heated to 50 C for 12 hours, cooled and partitioned between ethyl acetate and water. The organic layer is washed with water, brine, dried (sodium sulfate), filtered and concentrated. The residue is purified by preparative TLC eluting with 50% ether in hexanes to give {4-[6-Ethyl-5-(ethylpropoxy)-3-methoxypyrazin-2-yl]-3-methoxyphenoxy}trifluoromethane, a colorless oil (19 mg). NMR (CDCL3, 400 MHz) δ 0.98 (t, 6H), 1.22 (t, 3H), 1.78 (m, 4H) 2.80 (q, 2H), 3.80 (s, 3H), 3.88 (s, 3H), 5.05 (quintet, 1H), 6.8 (s, 1H), 6.90 (d, 1H), 7.37 (d, 1H); MS 345 (M+1).
