Procedure
2.5 g of 2-hydroxy-4-methoxybenzaldehyde, 6.8 g of K2CO3, 3.3 ml of chloroethanol and 33 ml of DMSO were heated for 8 hrs. to 80° C. Extraction with ethyl acetate and chromatography on silica gel with methylene chloride-acetone gave 2.1 g of 2-(2-hydroxy-ethoxy)-4-methoxy-benzaldehyde, m.p. 94° C., MS: 196 (M)+.
