Procedure

According to the procedure described in Example 1(a) for the preparation of 3-biphenyl-4-yl-furan, 4-bromopyridine (700 mg, 3.00 mmol) underwent coupling to 4-bromophenylboronic acid to give 2.38 g (100%) of 4-(4-bromo-phenyl)-pyridine as a yellow solid, which had an NMR that matched literature (Boy, P.; Combellas, C.; Thiebault, A.; Amatore, C.; Jutand, A. Tetrahedron Lett. 1992, 33, 491494) and was used without further purification. IR (KBr): 1593, 1474, 1412, 1075, 1006, 807, 756, 693, 498 cm−1.
