Procedure

2-[2-(3-(R)-Amino-piperidin-1-yl)-5-bromo-6-oxo-6H-pyrimidin-1-ylmethyl]-benzonitrile (Example 1) (80 mg, 0.21 mmol) and tributyltin hydride (83 μL, 0.31 mmol) were stirred in dry toluene (5 mL) under nitrogen. Tetrakis(triphenylphosphine)palladium(0) (36 mg, 0.013 mmol) and a catalytic amount of AIBN were added, and the reaction stirred at 108° C. for 24 h. Concentration in vacuo and purification by Prep HPLC gave 51.8 mg (59%) of the title compound as the TFA salt. 1H NMR (400 MHz, CDCl3): δ 8.40 (br s, 3H), 7.71 (d, 1H, J=6.4 Hz), 7.63 (d, 1H, 7.6 Hz), 7.57 (t, 1H, J=7.6 Hz), 7.40 (t, 1H, J=7.6 Hz), 7.33 (d, 1H, J=7.6 Hz), 6.25 (d, 1H, J=6.4 Hz), 5.36 (AB q, 2H, J=113.2, 15.2 Hz), 3.47-3.59 (m, 3H), 3.21-3.28 (m, 2H), 1.95-2.05 (m, 2H), 1.80-1.91 (m, 1H), 1.60-1.71 (m, 1H). MS (ES) [m+H] calc'd for C17H19N5O, 310; found 310.
