実験手順

5.0 g (28 mmol) of ethyl 2-pyridyloxyacetate were suspended in 100 ml of 2-heptanol, 1 ml of titanium tetraisopropoxide were added, and the mixture was stirred for 4 hours at 120° C. The excess 2-heptanol was subsequently distilled off under an oil pump vacuum, and the residue was purified by column chromatography. 6.2 g (90% of theory) of (1-methyl)hexyl 2-pyridyloxyacetate were obtained as a colorless oil.
