実験手順
A solution of 2,4,6-trichloropyrimidine (100 g, 545 mmol) in acetonitrile (2000 mL) was added triethylamine (166 g, 1636 mmol) at 0° C., The reaction mixture was stirred for 5 min at rt, then 3-bromopropan-1-amine hydrobromide (119 g, 545 mmol) was added portionwise. The reaction mixture was stirred for 1 h at rt, and filtered to provide a clear solution. Purification via FC afforded the title compound as a white solid (47 g, 30% yield).
