Reaktionsschritte
To a suspension of NaH (60% dispersion in mineral oil, 242mg, 6.32mmoles, 1.4eq) in dry CH2Cl2(15ml) was added (4-Methoxy-3-methylbenzyl)(triphenyl)phosphonium chloride (2.62g, 6.32mmoles, 1.4eq). This was allowed to stir at room temperature for 1.5hours followed by the dropwise addition of 4-[(tetrahydro-2H-pyran-2-yloxy)methyl]-2-[4-(trifluoromethyl)phenyl]-1,3-thiazole-5-carbaldehyde (1.68g, 4.51mmoles, 1eq) in anhydrous carbon tetrachloride (25ml). The resulting reaction mixture was refluxed overnight at which point (after cooling to room temperature) the reaction washed with 1N NaOH, H2O, brine, dried over Na2SO4and concentrated in vacuo to yield a >100% yield of a light green oil. The crude material was used without purification.
