Procedure
Hydrogen chloride was bubbled into an ice-cooled solution of 5-(4-acetylbenzyl)thiazolidine-2,4-dione (1.0 g, 4.0 mmol) and p-anisaldehyde (0.55 g, 4.0 mol) in ethanol (15 ml) for 1 hour. The solution was stirred overnight at room temperature, then diluted with water and the yellow precipitate of present title product collected and dried (1.37 g, 93%); m.p. 177°-180° C.
