실험 절차

Following the general procedure of Example 6B, 2.3 g. of 2,3-dihydro-2-hydroxy-4,5-dichlorobenzofuran and 17.3 g. of propyltriphenylphosphonium bromide were reacted to provide 840 mg. of 2-(2-pentenyl)-3,4-dichlorophenol which upon hydrogenation following the procedure of Example 6C provided 300 mg. of 2-pentyl-3,4-dichlorophenol. This phenol was then reacted with 5.1 mmoles of 6-bromohexanoic acid following the procedure of Example 1C to provide 58 mg. of the desired title product. NMR.
