Procedure

A solution of 3-butyl-8-chloro-1-[4-(1H-imidazol-4-yl)butyl]-7-(2-propen-1-yl)-3,7-dihydro-1H-purine-2,6-dione (150 mg, 0.38 mmol) in anhydrous DMF (3 ml) was treated with 1-(chloromethyl)-3-(trifluoromethyl)benzene (65 μl, 0.42 mmol) and DIPEA (73 μl, 0.42 mmol). The mixture was left to stir at rt under nitrogen for 3 days. The mixture was partitioned between EtOAc and 2M HCl (aq). The organic layer was separated, washed with brine, dried (MgSO4) and concentrated. The crude product was purified on a silica SPE column using a DCM to load the material onto the column and wash through the impurities then a 0-5% MeOH/DCM gradient to elute the compound. The product fractions were combined and concentrated and the residues dissolved in anhydrous DMF (3 ml). The solution was degassed then Pd(PPh3)4 (30 mg, 0.027 mmol) and morpholine (156 μl, 1.8 mmol) were added and the mixture left to stir at rt under nitrogen for 3 h. The crude product was purified by an aminopropyl SPE using MeOH to load the compound onto the column and wash through the impurities then a 0-5% AcOH/MeOH gradient to elute the product. The product fractions were combined and concentrated by high vacuum to leave the title compound as a white solid (18 mg, 9%).
