A suspension of 4-amino-dimethylphenylphosphine oxide (3.7 g, 2.2 mmol) in 15 mL of N,N-Dimethylacetamide and 3.6 mL of Diisopropylethylamine, was allowed to stirred at room temperature for 15 minutes until a clear solution was obtained. 2,4-Dichloro-5-(trifluoromethyl)pyrimidine (5.7 g, 2.6 mmol) was added in four portions over 5 minutes. The reaction mixture was stirred at 60 degrees for 1 hour. The reaction mixture was cooled to room temperature and filtered to obtain a white solid. The white solid was washed with 50 mL of water three times and followed by 50 mL of Ethyl ether three times. The white solid was dried under vacuum to yield desired product (3.8 g, 49% yield). MS ES+: m/z=350.
