Reaction Steps

A mixture of 1.23 g. of 2-methyl-3-hydroxy-4-hydroxymethylpyridine-5-acrylic acid, 1 g. of sodium metal, 5 ml. of carbon disulfide, and 75 ml. of absolute ethanol was refluxed for 26 hours. Concentrated hydrochloric acid (3 ml.) was added and the mixture was evaporated to dryness. The residue was extracted with 125 ml. of boiling ethanol and filtered hot. Evaporation of the extract gave a syrup which was crystallized from chloroform-ether to give 2-methyl-3-hydroxy-4-mercaptomethylpyridine-5-acrylic acid hydrochloride, m.p. 227°-228° C.
