Reaction Steps
To a stirred solution of 3-pentanol (88 mg, 1 mmol) in THF (1 mL) is added 60% sodium hydride (12 mg, 0.3 mmol) and after 0.5 h [4-(5-bromo-6-ethyl-3-methoxypyrazin-2-yl)-3-methoxyphenoxy]trifluoromethane (41 mg, 0.1 mmol) is added. The mixture is heated to 50° C. for 12 h, 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).
