反応手順

The reaction of ethyl 2-methylundecanoate (11.4 g, 0.05 mole) with 2,3-butanedione (4.73 g, 0.055 mole) is conducted in the manner described in Example I, and 16.6 g of a crude oil is obtained. The crude oil product is subjected to high pressure liquid chromatography on silica gel using 5% ethyl acetate in hexane as the eluant, yielding a pure product (9.2 g, 59%), b.p. 100° C. (Kugelrohr air bath temperature) at 0.01 mm Hg.
