Procedure
To a stirred solution of 2,4-dichloropyrimidine (500 mg, 3.38 mmol, 1 eq) in THF (15 mL) was added (S)-1-phenylethylamine. After 48 h the precipitate was filtered off and washed with THF. The THF was removed under reduced pressure and the material was purified by silica gel chromatography (eluted with 4:1 hexanes/acetone) to give 167 mg of the desired product. [Note: 2-[(S)-1-phenylethylamino]-4-chloropyrimidine is the faster but minor regioisomer. The major, slower product is 2-chloro-4-[(S)-1-phenylethylamino]pyrimidine.]
