Procedure

To a solution of EXAMPLE 15B (2.88 g), 4-chlorophenylboronic acid (1.88 g) and Pd(Ph3P)4 (0.578 g) in toluene (40 mL) and ethanol (10 mL) was added 2N Na2CO3 (10 mL). The mixture was stirred at reflux overnight. The mixture was diluted ether (300 mL) and washed with water, brine and dried over Na2SO4. After evaporation of solvent, the residue was loaded on a column and eluted with 3% ethyl acetate in hexane to give the product.
