実験手順

A solution of the product of Step A (0.37 g, 0.5 mmol) and but-3-yn-1-ol (0.12 ml, excess) in a mixture of DMF (5 ml) and DIPEA (0.5 ml) was degassed with N2 and Cl2Pd(PPh3)2 (0.07 g) was added, followed by catalytic amount of CuI and the mixture was stirred for 16 h at room temperature. The reaction was quenched with saturated NH4Cl solution and diluted with H2O followed by the extraction with EtOAc (100 ml). The organic layer was separated, dried over MgSO4, filtered and the filtrate was evaporated to dryness and the residue was purified by FCC (SiO2, hexane/EtOAc) to give the product (0.11 g, 60%), as creamy paste. 1H-NMR (CDCl3) 7.66 (d, 2H, J=8.43 Hz); 7.51 (d, 2H, J=8.43 Hz); 3.81 (b, 2H); 3.01-2.86 (m, 2H); 2.71-2.67 (m, 4H); 2.50-2.10 (m, 2H); 1.94-1.82 (m, 5H); 1.52-1.48 (m, 1H); 1.18 (s, 3H); 1.02 (s, 3H).
