실험 절차
4-{[4-(Cyclopentylamino)-5-nitropyrimidin-2-yl]amino}trans-cyclohexan-1-ol (2.18 mmol, 700 mg) was dissolved in 20 ml EtOH and hydrogenated overnight at 1 bar with Pd/C (10%) as catalyst. The catalyst was filtered and the solvent evaporated to give the desired product (635 mg, 100% yield) which was carried on to the next step without further purification. ES-MS: 292 (M+1). This reduction can be also accomplished using the following procedure: Na2S2O4 (140.0 mmol, 14 eq.) is dissolved in 150 mL water and 75 mL dioxane and 7.5 mL NH4OH solution are added. The corresponding nitro compound (10.0 mmol, 1 eq.) is added and the reaction mixture is stirred for 12 to 72 hours. Dioxane is evaporated and the product is extracted by using EtOAc or brine/THF. The organic phase is dried over MgSO4 and evaporated to give the desired product.
