To a solution of the product of Step E (0.018 g; 0.033 mmol), NaI (0.015 g; 0.0981 mmol) in anhydrous CH3CN (0.6 ml), Me3SiCl (0.08 ml) was added at room temperature with stirring under N2. After stirring for 30 min MeOH (0.5 ml) was added and solvents were removed under reduced pressure. The residue was purified by FCC (SiO2; NH4OH saturated CH2Cl2:MeOH 95:5) to give the title compound (0.0066 g; 49%) as colourless solid. 1H-NMR (CDCl3+CD3OD) 0.93 (tr, 3H, J=(Hz); 1.67-1.81 (m, 2H); 2.81 (tr, 2H, J=9 Hz); 2.99 (broad s, CD3OH); 3.07 (s, 2H); 3.26-3.65 (m, 8H); 6.74 (d, 1H, J=9 Hz); 7.15 (m, 1H); 7.31 (d, 1H, J=9 Hz); 7.42 (d, 1H, J=9 Hz); 8.32 (dd, 1H, J=3, 9 Hz); 9.33 (d, 1H, 3 Hz).
