実験手順
4-Bromo-thiazol-2-ylamine (100 mg, 0.34 mmol) was combined with 57 mg (0.51 mmol) of 2-furan boronic acid. To this mixture was added 5 mL of MeOH, 1 mL of sat. NaHCO3 (aq), and 0.8 mL of DMF. Reaction mixture was degassed and Pd[P(Ph)3]4 (25 mg) was added. Reaction mixture was heated at 70° C. for 7 hours. The reaction mixture was brought to room temperature and filtered. The filtrate was evaporated and purified using reverse phase HPLC.
