실험 절차

A mixture of the product of Step C (0.2 g; 0.41 mmol), 1-octyne (0.091 ml; 0.62 mmol), Cl2Pd(PPh3)2 (0.02 g; 0.028 mmol) and CuI (0.005 g; 0.026 mmol) in anhydrous DMF (2 ml) was degassed under reduced pressure and saturated with dry N2. After addition of DIPEA (0.5 ml), the resulting mixture was stirred overnight at room temperature under N2. The solvents were removed in vacuo and the residue was diluted to 15 ml with EtOAc and washed with 5% citric acid, 5% NaHCO3, H2O, brine and dried over anhydrous MgSO4 and filtered. The filtrate was evaporated to dryness under reduced pressure and the residue was purified by FCC (SiO2; hexane/EtOAc; 9:1) to give the title compound (0.17 g; 89%) as a colourless syrup. 1H-NMR (CDCl3) 0.93 (m, 3H); 1.34-1.64 (m, 8H); 2.4 (tr, 2H, J=7.1 Hz); 3.94 (s, 4H); 7.0-7.64 (m, 18H).
