Reaction Steps
Triethylamine (0.4 ml, 2.85 mmol) was added to a solution of compound 1 (300 mg, 0.96 mmol) in ice-cold 1,2 dichloroethane. A solution of stearoyl chloride (450 mg, 1.49 mmol) in 1,2-dichloroethane was added drop-wise to the ice-cold solution of compound 1. The reaction mixture was stirred at room temperature for 16 h. After completion of the reaction, 10% potassium carbonate solution (10 ml) was added, and stirred for 30 min. The organic phase was separated, dried with anhydrous sodium sulfate, and concentrated to obtain a shiny solid of 25 (373 mg, 67% yield). 1H NMR (300 MHz, CDCl3): δ 7.92, 7.89 (2s, 2H, C═CH), 7.50-7.35 (m, 4H, Ar—H), 7.30-7.14 (m, 4H, Ar—H), 4.79, 4.55 (2s, 4H), 2.44 (td, 2H, J=7.3, 2.3), 2.09 (t, 2H, J=7.6), 1.65 (t, 2H, J=7.0), 1.41 (t, 2H, J=7.3), 1.40-1.05 (m, 24H), 0.87 (t, 3H, J=6.7, CH3). 13C NMR (75 MHz, CDCl3): δ 172.05, 133.77, 133.40, 133.48, 130.76, 130.23, 124.29, 116.39, 116.09, 115.81, 46.45, 43.48, 35.26, 33.08, 31.92, 29.69, 29.37, 28.86, 25.06, 24.21, 22.69, 14.12. ESI Mass calculated for C37H50F2NO2(M+H)+578.38. found 578.40.
