実験手順

5.75 g (46.3 mmol) of 1-(2-methyl-1-imidazolyl)ethanone was dissolved in 600 ml tetrahydrofuran and photolyzed in a quartz flask with a short wave u.v. light source (2537 nm) for 18 hours. The tetrahydrofuran solution was concentrated in vacuo to an oil and chromatographed on silica gel using 5% methanol in chloroform as eluent to give 2.6 g (45%) 1-(2-methyl-4-imidazolyl)ethanone, mp 123°-5°.
