Procedure

Using analogous reagents and reaction conditions as described in Example 1 above, 1-(4-cyclopropyl pyridin-3-yl)-3-(2,6-dichloropyridin-4-yl)imidazolidin-2-one (I-46a: 100 mg, 0.2865 mmol) was reacted with cyclopropyl boronic acid (74 mg, 0.8593 mmol), Pd(PPh3)4 (7 mg, 0.0057 mmol), sodium carbonate (69 g, 0.6590 mmol) and toluene (5 mL) in seal tube at 120° C. for 12 hours. Purification by column chromatography on silica gel (1% methanol in chloroform), followed by preparative HPLC afforded 20 mg of the product (20% yield).
