Versuchsvorschrift
The title compound obtained by treating 2-(methylsulfonyl)-4-(amino)-5-(4-chlorophenyl)-6-(2,4-dichlorophenyl)pyrimidine (Example 32, Step A,) with 3,4-difluorobenzyl alcohol by the same general procedure described in Reference Examples 6 and 7. Workup and flash column chromatography on silica gel (eluted with 80/20 hexanes/ethyl acetate) afforded 2-(3,4-difluorobenzyloxy)-4-(amino)-5-(4-chlorophenyl)-6-(2,4-dichlorophenyl)pyrimidine. HPLC/MS: m/e=494 (M++1); Rt=3.91 min. 1H-NMR 500 MHz (CDCl3): δ 5.10 (bs, 2H), 5.38 (s, 2H), 7.0-7.10 (m, 2H), 7.11-7.23 (m, 6H), 7.15-7.19 (m, 2H).
