Yield:3740-92-9 95%
Reaction Conditions:
in trichlorophosphate
Steps:
1 Synthesis of Chloroacetamide Intermediate 6.
4,6-Dichloro-2-phenylpyrimidine (3): A slurry of diol 2 (39.08 g; 0.208 mol) in phosphorus oxychloride (124 mL; 1.33 mol) was heated from 75-120° C. over 45 min. After 20 h at 120° C. the volatiles were removed in vacuo. The resulting tan solid was added to crushed ice (600 mL) and this suspension was stirred for 2 h at rt, collected by filtration, washed with water and dried to a constant weight under high vacuum giving a tan solid (44.34 g; 95%). 1H NMR (200 MHZ, CDCl3) δ 8.44 (m, 2H), 7.51 (m, 3H), 7.27 (s, 1H).
