실험 절차
N-Methoxy-2-(3-methoxy-propyl)-N-methyl-6-trifluoromethyl-nicotinamide (156 mg, 0.509 mmol) was reacted with 1M-LAH in THF solution to give 2-(3-methoxy-propyl)-6-trifluoromethyl-pyridine-3-carbaldehyde quantitatively as oil. The crude product was used directly in the following reaction. 2-(3-Methoxy-propyl)-6-trifluoromethyl-pyridine-3-carbaldehyde was reacted with methyl(triphenylphosphoranylidene)acetate (204 mg, 0.61 mmol) to give 3-[2-(3-methoxy-propyl)-6-trifluoromethyl-pyridin-3-yl]-acrylic acid methyl ester (124 mg, 80%).
