With selenium(IV) oxide; potassium tert-butylate; In hexane; | EXAMPLE 3 This Example illustrates an alternative synthesis of (E)-methyl 3-methoxy-2-[2-(3-methylphenoxy)phenyl]propenoate. A mixture of methyl ortho-bromophenylacetate (4.10 g, prepared as described in Example 1) and selenium dioxide (4.92 g) was stirred for 25 hours at 190 C. After cooling, the mixture was diluted with dichloromethane (100 ml) then filtered through `Supercel`. The filtrate was washed successively with saturated aqueous sodium bicarbonate (*2) and brine, then dried and concentrated to give a yellow liquid (3.60 g) containing (52% by GC-MS) <strong>[122394-38-1]methyl (2-bromobenzoyl)formate</strong> and unreacted methyl ortho-bromophenylacetate. Potassium tert-butoxide (2.33 g) was added to a vigorously-stirred suspension of (methoxymethyl)triphenylphosphonium chloride (7.90 g) in ether (80 ml) at room temperature. After 15 minutes, a solution of the crude <strong>[122394-38-1]methyl (2-bromobenzoyl)formate</strong> (3.60 g) in ether (10 ml) was added in a single portion. After a further 15 minutes, the reaction mixture was poured into water (150 ml), the aqueous and organic layers were separated, and the former was extracted with a further portion of ether (100 ml). The combined ether layers were washed successively with water (*2) and brine, then dried and concentrated to give a yellow oil (5.81 g) containing, in a ratio of about 6:5, the (E)- and (Z)-isomers respectively of methyl 2-(2-bromophenyl)-3-methoxypropenoate. Chromatography using ether:hexane (1:1) as eluant allowed the pure (Z)-isomer (0.450 g) to be isolated as a pale yellow oil, IR (film) 1712, 1638 cm-1, 1 H n.m.r delta 3.71 (3H, s), 3.95 (3H, s), 6.57 (1H, s) p.p.m. |
