Reaction Steps
To a sealed tube containing 2-[5-bromo-1-benzyl-1H-indole-2carboxylic acid (100 mg, 0.303 mmol) and 2-thiopheneboronic acid (116 mg, 0.909 mmol), (C6H5)4Pd (42 mg, 0.036 mmol), Na2CO3 (2,42 mmol) in a mixture of benzene-ethanol-H2O (5/1/2=v/v, 4.5 mL) was heated at 100° C. for 23 h. The mixture was poured onto diethyl ether and adjusted to pH 3 before extracting with diethyl ether. The organic layer was washed with NaH2PO4, dried over MgSO4 and evaporated to give the crude product which was purified on silica gel column (15% EtOAc in hexane with 1% HCOOH) to give 65 mg of the product.
