実験手順

Compound 11 (242 mg, 0.716 mmol), 1-(2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)ethyl)pyrrolidine 25 [prepared by Specific Method A2] (500 mg, 1.58 mmol), K2CO3 (247 mg, 1.79 mmol), and Pd(dppf)2Cl2 (524 mg, 0.072 mmol) were combined in a pyrex tube. After purging with N2, DMF (7.3 mL) and H2O (1.45 mL) were added and the tube was sealed. The mixture was heated at 80° C. for 5 h. After cooling to RT, CH2Cl2 was added and the organic layers were washed with H2O, followed by brine. The organic layers were then dried over Na2SO4 and concentrated to a brown oil. Flash chromatography (SiO2, gradient eluent: 0-15% MeOH in CH2Cl2), followed by trituration with EtOAc and filtration afforded compound 26.
