Reaction Steps

A mixture of 1-[2-methyl-2-((R)-1-oxiranylmethoxy)-propyl]-3-nitro-1H-pyrazole (0.3 g, 1.24 mmol), and ethyl acetate (15 mL), ethanol (15 mL) was subjected to the H-Cube (Thales Nano) at 1 mL/min at 10° C., 10 psi hydrogen. The first time through not completely reduced. Resubjected and complete reduction of nitro group by NMR. Solvent was removed under reduced pressure to afford 1-[2-methyl-2-((R)-1-oxiranylmethoxy)-propyl]-1H-pyrazol-3ylamine as an oil (0.27 g, 100%).
