Participants

Reaction Steps

A suspension of sodium hydride (15 mg, 0.36 mmole) in DMF (1.5 mL) was treated with 3-ethyl-6-hydroxy-7-propylbenz-[4,5]-isoxazole (68 mg, 0.33 mmole) and the mixture stirred at room temperature for 10 minutes under a nitrogen atmosphere. A solution of methyl 4-(4-methansulfonyloxybutyl)phenylacetate (100 mg, 0.33 mmole) in DMF (0.5 mL) was added and the mixture stirred at 80° C. for 5 hours. The cooled reaction mix was dissolved in ethyl acetate and washed with water (twice), brine, dried over magnesium sulfate and concentrated in vacuo to an oil. The crude product was purified by thin layer chromatography on silica gel eluting with hexane:ethyl acetate (4:1) to give the title compound (80 mg) as an oil. NMR (CDCl3): δ 0.97 (t, 3H); 1.44 (t, 3H); 1.71 (m, 2H); 1.87 (m, 4H); 2.71 (t, 2H); 2.88 (t, 2H); 2.97 (q, 2H); 3.62 (s, 2H); 3.71 (s, 3H); 6.89 (d, 1H); 7.18 (d, 2H); 7.22 (d, 2H); 7.39 (d, 1H).
