반응 단계

1.0 mmol of (1-methoxy-2,2- dimethylethenyl)-oxytrimethylsilane was placed in a 20-ml flask, followed by the addition of 3 ml of pyridine as a solvent. 1.3 mmol of benzenediazonium tetrafluoroborate was added to the flask. The obtained mixture was stirred at 0° C. in a nitrogen atmosphere for 2 hours. The reaction mixture was diluted with diethyl ether and washed with 1.5 N hydrochloric acid, water and a saturated aqueous solution of common salt successively. The obtained organic phase was dried over magnesium sulfate and distilled under a reduced pressure to remove the solvent. The obtained oily mixture was subjected to silica gel thin-layer chromatography to obtain 0.90 mmol of methyl 2-methyl-2-phenylazopropionate.
