Reaction Steps

The title product was prepared by reaction of N-methyl-4-(4-phenyl-1-piperidin-4-yl-1H-imidazol-5-yl)pyrimidin-2-amine (C26) with 2-(chloromethyl)-pyrimidine according to the general procedure for the synthesis of 4-{4-(4-fluorophenyl)-1-[1-(pyrimidin-2-ylmethyl)piperidin-4-yl]-1H-imidazol-5-yl}pyrimidin-2-amine (3) in Example 3. In this case, after the reaction cooled to room temperature, it was diluted with dichloromethane (20 mL) and water (2 mL). The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo to provide a light yellow solid, which was dissolved in a small volume of dichloromethane. Addition of heptane caused a solid to precipitate; this mixture was stirred for 30 minutes and then the solid was collected by filtration, washed with heptane and washed with diethyl ether to provide the product as a light yellow solid. Yield: 106 mg, 0.248 mmol, 34%.
