実験手順

To a solution of the product of Example 13, Step B (0.11 g; 0.32 mmol) in anhydrous DMF (0.6 ml) 60% NaH in mineral oil (0.02 g; 0.5 mmol) was added and the mixture was stirred for 1 h at room temperature under N2. To it, a product of Step A (0.13 g; 0.383 mmol) was added and the resulting mixture was stirred for 3 days at ˜55° C. under N2, cooled to room temperature and diluted to 15 ml with Et2O, washed with H2O, brine, dried over anhydrous MgSO4 and filtered. The filtrate was evaporated to dryness under reduced pressure and the residue was purified by FCC (SiO2, CH2Cl2/EtOAc 8:2) to give the title compound (0.07 g; 37%) as a colourless solid. 1H-NMR (CDCl3) 1.23 (s, 9H); 1.46 (s, 3H); 1.53 (s, 3H); 3.71 (d, 2H, J=11.8 Hz); 3.84-3.94 (m, 15H); 4.12 (s, 1H); 4.76 (s, 2H); 6.96 (dd, 1H, J=2.2, 8.8 Hz); 7.06 (s, 2H); 7.16 (d, 1H, J=2.2 Hz); 7.44 (s, 1H); 8.24 (d, 1H, J=8.8 Hz).
