To a solution of 4,6-dimethoxy-2-(2-(4-nitro-1H-pyrazol-1-yl)ethoxy)pyrimidine (2.05 g, 6.93 mmol), in EtOAc (3.0 mL, degassed) and EtOH (9 mL, degassed), PtO2 (135 mg, 0.70 mmol) was added and the reaction mixture was stirred at rt under a H2-atmosphere for 3 h. The mixture was diluted with EtOH, filtered over celite and the filter cake was rinsed with EtOH. The filtrate was concentrated to obtain the title compound as a red oil. LC-MS conditions A: tR=0.58 min, [M+H]+=266.02.
