A mixture of 5-iodo-1-{3-[(1S,5R)-1-(4-trifluoromethyl-phenyl)-3-aza-bicyclo[3.1.0]hex-3-yl]-propyl}-1H-pyrimidine-2,4-dione (Prep 40, 150 mg, 0.3 mmol), 2-fluoro-5-chloropyridine-3-boronic acid (142 mg, 0.9 mmol), KF (157 mg, 2.7 mmol), and Pd(OAc)2 (20 mg) in degassed MeOH (4 ml) was placed in a microwave oven and warmed at 120° C. for 25 minutes. The mixture was filtered, MeOH was evaporated and the crude partitioned between brine and ethyl acetate. The organic phase was dried (Na2SO4) and evaporated; the crude was purified by flash chromatography with ethyl acetate-NH4OH (0.5%) to give the title compound (10 mg, 6% yield).
