Reaction Conditions

Reaction Steps

To a solution of 4-(piperazin-1-yl)-6-(3-trifluoromethylphenyl)-pyrimidine-2-carbonitrile trifluoroacetic acid salt (Example 1; 50 mg) in acetonitrile (1 ml) was added diisopropylethylamine (39 μl) and 2-bromopropane (15.5 μl). The resulting solution was subjected to microwave heating at 150° C. for 5 mins. Sodium iodide (2 mg) was added and the reaction mixture was subjected to further heating at 180° C. for 30 mins. Reaction mixture was concentrated in vacuo and the residue was dissolved in methanol and purified using the prep-HPLC to give 4-(4-isopropyl-piperazin-1-yl)-6-(trifluoromethyl-phenyl)-pyrimidine-2-carbonitrile trifluoroacetic acid salt (10 mg).
