Reaction Steps

The compound of example 219 (10 g, 0.044 mol), 4,4,5,5-tetramethyl-2-(4-nitrophenyl)-1,3,2-dioxaborolane (13.16 gm, 0.0528 mole) and Pd(dppf)Cl2:CH2Cl2 (1.07 g, 0.00132 mol) were taken in DMF (250 mL) under an argon atmosphere. To this reaction mixture, degassed 2M solution of Na2CO3 (14 g, 0.132 mol, 66.5 mL) was added. The reaction mixture was stirred at 80-85° C. for 1 to 1.5 h. After completion of the reaction, water was added and the product obtained was extracted with ether. The combined ether layer was washed with brine and dried over anhydrous Na2SO4 or MgSO4. The solvent was evaporated and the product was purified by column (silica gel, 20% ethyl acetate in petroleum ether) to obtain the title compound.
