Reaction Steps

A mixture of 13.3 g of 2,4-thiazolidinedione and 12.3 g of o-anisidine was dissolved in 100 ml of warm ethanol at 55° to 70° C. The solution was cooled to about 30° C, and 9.1 ml of 37% formaldehyde solution was added and stirred overnight. The resulting precipitate was filtered to give 22.5 g of N-(2-methoxyphenylaminomethyl)-2,4-thiazolidinedione, mp 88.5°-91° C; identified by IR and NMR.
