Reaction Steps

A mixture of Example 490 (0.05 g, 0.118 mmol), 3-(piperidin-1-ylmethyl)-phenylboronic acid pinacol ester hydrochloride (0.0478 g, 0.141 mmol), potassium phosphate (0.1 g, 0.471 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.0082 g, 0.0071 mmol) was degassed under 3 cycles of nitrogen and vacuum. DME (1.2 mL) and water (0.3 ml) were added and the mixture was degassed as before. The mixture was heated to 120° C. under microwave irradiation in a sealed tube for 1 h. Water (15 mL) and DCM (15 mL) were added. The aqueous fraction was separated and extracted with DCM (2×10 mL). The combined organic fractions were filtered through a Whatman 1μ PTFE tube and concentrated in vacuo. The residue was purified by preparative HPLC (Method 6) to give the title compound (0.0243 g, 40%) as a colourless solid. δH (CDCl3) 7.76 (1H, s), 7.45 (1H, s), 7.41-7.31 (2H, m), 7.30-7.25 (1H, m), 6.57 (1H, s), 5.28 (1H, s), 4.37-4.32 (2H, m), 4.21-4.16 (2H, m), 3.78 (3H, s), 3.54 (2H, s), 2.84 (2H, s), 2.49-2.37 (4H, m), 1.64-1.54 (4H, m), 1.48-1.35 (8H, m). LCMS (ES+) 519.3 (M+H)+, RT 2.32 minutes (Method 1).
