Reaction Steps

A mixture of tert-butyl N-[5-bromo-3-(5-methyl-1,2,4-oxadiazol-3-yl)pyrazin-2-yl]-N-tert-butoxycarbonyl-carbamate (200 mg, 0.4383 mmol) in DMF (1.562 mL) was treated with piperazine (377.5 mg, 4.383 mmol) and the reaction mixture heated at 100° C. for 30 minutes. The reaction was allowed to cool to RT and diluted with EtOAc/Water and the layers separated. The organic layer was washed with water (3×), dried (MgSO4), filtered and concentrated in vacuo. The material was used crude in the next step (150 mg, 67% Yield). 1H NMR (400.0 MHz, CDCl3) d 1.37 (18H, s), 2.73 (3H, s), 3.14 (4H, m) ppm; MS (ES+) 462.14
