Procedure

To a mixture of 200 ml of tetrahydrofuran, 26.00 g of pyridine and 20.70 g of glycine methyl ester hydrochloride was added a solution of 16.00 g of 3-formylbenzoic acid chloride in 20 ml of tetrahydrofuran at 10° C. After stirred at room temperature for 60 hours, insolubles were filtered and the filtrate was concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to obtain 4.23 g of oily 3-[[(methyoxycarbonylmethyl)amino]carbonyl]benzaldehyde [Compound No. (b)].
