Reaction Steps
To a solution of 4-nitrobenzyl alcohol (666 mg) in DMF (8 ml) was added potassium carbonate (800 mg) followed by a solution of (E)-methyl 2-[2-(6-methanesulphonylpyrimidin-4-yloxy)phenyl]-3-methoxypropenoate (1.0 g, prepared as described in Example 1) in DMF (3 ml). The reaction mixture was heated to 60° C. under an atmosphere of nitrogen for 5½ hours, cooled and then poured into water (40 ml). The resulting mixture was extracted with ether (×3) and the combined ether layers were dried and evaporated to yield an orange oil. Chromatography (eluent ether-hexane, 7:3) gave (E)-methyl 2-[2-(6-(4-nitrobenzyloxy)pyrimidin-4-yloxy)phenyl]-3-methoxypropenoate (532 mg) as a glass which solidified on standing; m.p. 96-98° C.; 1H NMR: δ 3.55 (3H, s), 3.75 (3H, s), 5.50 (2H, s), 6.15 (1H, s), 7.15 (1H, d), 7.3 (3H, m), 7.45 (1H, s), 7.58 (2H, d), 8.22 (2H, d), 8.42 (1H, s) ppm; IR maxima: 1700, 1620, 1560, 1340 cm−1; mass spectrum m/e 437 (M+).
