실험 절차

To a solution of the above prepared 3-chloropropyl 5-(tetradecyloxy)furan-2-carboxylate (0.272 g, 0.68 mmol) in 6 mL of N,N-dimethylformamide was added morpholine (0.535 mL, 6.1 mmol) and sodium iodide (10 mg). The resulting solution was stirred at 55° C. for 36 hrs at which time HPLC analysis of the reaction mixture indicated near complete consumption of the starting material. The solution was diluted with EtOAc (30 mL), brine (10 mL) and water (10 mL) such that both phases were clear solutions. The phases were separated and the organic phase was washed with water (20 mL) and brine (20 mL) and then dried and concentrated. The crude material was purified by flash chromatography eluting with 5-40% EtOAc in hexanes to yield 0.217 g of the title compound. 1H NMR (300 MHz, CDCl3) δ: 7.10 (d, 1H), 5.30 (d, 1H), 4.30 (t, 2H), 4.10 (t, 2H), 3.7 (t, 4H), 2.40-2.50 (m, 6H), 1.90 (p, 2H), 1.76 (p, 2H), 1.18-1.50 (m, 22H), 0.89 (t, 3H).
