Reaction Steps

A solution of 0.31 g of SOCl2 in 2 ml of benzene was added dropwise at 0° C. under nitrogen atmosphere to a solution of 0.22 g of 5-methylfuran-2-carboxylic acid, prepared following the method described by Robert et al., Eur. J. Med. Chem. 30, 915-924 (1995), in 5 ml of benzene. The mixture was stirred at 80° C. for 1 hour and the excess SOCl2 was then distilled off. The residue (0.24 g, 97% of theory) was utilized for the next step without further purification.
