2,4,5-Trimethyl-3-furancarbonyl chloride was prepared by refluxing 2,4,5-trimethyl-3-furancarboxylic acid (20.0 g) with thionyl chloride (20 ml) in toluene (75 ml) for 3 hours. The toluene and excess thionyl chloride were removed on a rotary evaporator and the residue distilled (b.p. 95°-97° C. at ca. 12 mm).
