Procedure

To a stirred solution of 6-(2,3-dihydro-1H-inden-2-ylamino)nicotinaldehyde (160 mg) and malonic acid (84 mg) in pyridine (6 mL) was added piperidine (0.01 mL), and the mixture was stirred at 100° C. for 2 hours. The solvent was evaporated in vacuo and the resulting powder was collected by filtration to give (2E)-3-[6-(2,3-dihydro-1H-inden-2-ylamino)-3-pyridinyl]acrylic acid (190 mg) as a pale yellow powder.
