Versuchsvorschrift
Diethyl 6,7-dihydrothiazolo[5,4-c]pyridine-2,5(4H)-dicarboxylate (1.76 mmol) in 3.5 N KOH solution (3 ml) was refluxed for 3 h (monitored by TLC). The reaction mixture was cooled to 0° C. and acidified with conc. HCl. The solid was collected by filtration and dried to yield the desired product. Yield: 60%.
