Participants

Reaction Steps

2-Methylthio-4-(2,4-dichlorophenyl)-5-(4-chlorophenyl)pyrimidine (from Reference Example 3) was reacted with 4-chlorobenzyl alcohol according to the procedures described in Example 1 to afford 2-(4-chlorobenzyloxy)-4-(2,4-dichlorophenyl)-5-(4-chlorophenyl)pyrimidine as the higher Rf product (95/5 hexane/ethyl acetate TLC). HPLC/MS: m/e=477 (M+1); Rt=4.91 min; 1H-NMR 500 MHz (CDCl3): δ 5.50 (s, 2H), 7.02 (d, J=9 Hz, 2H), 7.22 (d, J=9 Hz, 1H), 7.22-7.30 (m, 4H), 7.40 (d, J=9 Hz, 2H), 7.50 (d, J=9 Hz, 2H), 8.62 (s, 1H). 2-(4-Chlorobenzyloxy)-4-(2-chloro-4-thiomethyl phenyl)-5-(4-chlorophenyl)pyrimidine was obtained as the lower Rf by-product of the thiomethyl anion displacement of the 4-chloro substituent on the 4-(2,4-dichlorophenyl) ring. HPLC/MS: m/e=489 (M+1); Rt=4.81 min; 1H-NMR 500 MHz (CDCl3): δ 2.52 (s, 3H), 5.50 (s, 2H), 7.03 (m, 2H), 7.10-7.20 (m, 2H), 7.24-7.30 (m, 3H), 7.38 (d, J=9 Hz, 2H), 7.50 (d, J=9 Hz, 2H), 8.60 (s,1H).
