Procedure

1.5 g (2.883 mmol) of 405 and 1.112 g (4.324 mmol) of 2-(t-butylamino-sulfonyl)phenylboronic acid are dissolved in 100 ml of ethylene glycol dimethyl ether, treated with 63 mg (0.086 mmol) of PdCl2(dppf) and 20.0 ml of 2N sodium carbonate solution and then stirred at 110° C. under a nitrogen atomsphere for 3 h. After customary work-up, 1.32 g (75.6%) of 406 are thus obtained as crystals having a melting point of 173-174° C.; MS(FAB)=606.
