Reaction Steps

2-[2-(3-(R)-Amino-piperidin-1-yl)-5-bromo-6-oxo-6H-pyrimidin-1-ylmethyl]-benzonitrile (189 mg, 0.49 mmol), trimethylsilylacetylene (103 μL, 0.73 mmol), triphenylphosphine (4 mg, 0.02 mmol), and triethylamine (102 μL, 0.73 mmol) were stirred in THF (4 mL) in a flask purged with nitrogen. Dichlorobis(triphenylphosphine)palladium(II) (17 mg, 0.024 mmol) was added, and after 10 min copper iodide (2 mg) was added. The reaction stirred for 18 h at r.t. The solution was diluted with EtOAc, washed with brine, dried (MgSO4), and concentrated in vacuo. Purification by silica gel chromatography (5% MeOH/CHCl3) gave 168 mg (85%) of the title compound as a clear oil. MS (ES) [m+H] calc'd for C22H27N5OSi, 406; found 406.
