1-(6-methoxypyridin-3-yl)-2-nitro-propan-1-ol (2.20 g, 10.37 mmol) was dissolved in methanol (410 mL) and hydrogenated using a H-Cube™ hydrogenation reactor (THALES nanotechnology) equipped with a cartridge of 10% Pd/C. The flow rate was set to 0.8 mL/min, temperature 80° C. and full the hydrogen production at full mode. After evaporation of the solution diastereomers can be separated on preparative HPLC (XTerrra C18, 19×50 mm) using a gradient of 5-30% acetonitrile in water (+1% NH3) gave the pure subtitle compound (448 mg, 24%).
