To a solution of 3-bromo-4-[5-(3-hydroxypropyl)-imidazol-1-ylmethyl]benzonitrile (1.02 g, 3.2 mmol) that is prepared by alkylation of imidazole from Example 21 with bromide described in Example 1C followed by removal of the silyl protecting group by analogy to the first step in Example 3C in DME (10 mL) is added phenylboronic acid (586 mg, 4.8 mmol), aqueous Na2CO3 (2M, 4.8 mL, 9.6 mmol), and PS—PPh3-Pd (O) resin (0.13 mmol/g, 1 g). The reaction mixture is run in a microwave at 130° C. for 20 min. The mixture is partitioned between EtOAc and brine. The organic layer is washed with brine, dried over Na2SO4 and concentrated to give oil.
