Reaction Steps

A solution of 4-nitro-1-(tetrahydro-pyran-2-yl)-1H-pyrazole-3-carboxylic acid [4-(tetrahydro-pyran-2-yloxy)-cyclohexyl]-amide (0.3 g; 0.71 mmol) in methanol (25 ml), was treated with 10% palladium on carbon (30 mg) then hydrogenated at room temperature and pressure overnight. The catalyst was removed by filtration and washed three times with methanol. The filtrate was evaporated to give 0.264 g of the required product. (LC/MS: Rt 2.39, [M+H]+ 393).
