Dimethylsulfoxide (125 μl) was dissolved in dichloromethane (10 ml) and cooled to −78° C. Oxalyl chloride (80 μl) was added dropwise and the mixture was stirred for 15 minutes. Trimethylsilylmethyl 2-(1-hydroxy-3-methylbutyl)furan-3-carboxylate (200 mg) in dichloromethane (10 ml) was added and the mixture was stirred for 20 minutes. Triethylamine (0.49 ml) was added. The mixture was stirred for 20 minutes, and then allowed to warm to ambient temperature. The mixture was poured onto water and then extracted thrice with ethyl acetate. The organic phases were combined, washed with brine, dried, filtered and evaporated to give the sub-title compound (170 mg).
