Reaction Steps

To a stirred solution of 5-ethynyl-2-aminopyrazine (18 mg; 0.151 mmol), in ethyl acetate (500 μL) was added triethylamine (63 μL; 0.45 mmol) and Pd(OH)2 (0.01 mmol; 20% wt on carbon). The reaction was placed under a hydrogen atmosphere at 45 psi and shook for 6 hours. The reaction was filtered and concentrated under reduced pressure to yield an off white solid (84% yield).
