Procedure

To a solution of didodecylamine 66 (25 g, 70 7 mmol) and diisopropylethylamine (18 g, 141 mmol) in anhydrous CH2Cl2 (700 mL) at −10° C., a solution of acryloyl chloride (7.68 g, 85 mmol) in CH2Cl2 (100 mL) was added dropwise over a period of 20 min. After the completion of the addition the reaction mixture was stirred for 4 h at 0° C. after which the TLC of the reaction mixture showed the completion of the reaction. The reaction mixture was washed with satd. NaHCO3 solution (200 mL), water (200 mL), brine (100 mL) and dried over NaSO4. Concentration of the organic layer provided the product 71 (28.4 g, 100%) which was used as such in the next step. 1H NMR CDCl3 δ 0.94 (t, J=6.5 Hz, 6H), 1.05-1.69 (m, 40H), 3.15-3.60 (dt, 4H), 5.64 (d, 1H), 6.36 (d, 1H), 6.63 (m, 1H).
