Participants

Reaction Steps

5.62 g of 4-phenylsulfanyl-phthalic acid (20.5 mmol) and 1.55 g of glycine (20.5 mmol) were ground thoroughly together in a mortar. Then the mixture was heated to 210° C. to 220° C. in an oil bath. The molten mass was stirred with a spatula at this temperature for 15 min before it was allowed to cool to ambient temperature in vacuo. 6.30 g of the title compound were obtained; MS-(−)-ion: M−1=311.8.
