Reaction Steps
5-(3-dimethylamino-acryloyl)thiophene-2-carboxylic acid (200 mg, 0.888 mmol), N-m-tolylguanidine (71.1 mg, 1.77 mmol) and NaOH (264 mg, 1.77 mmol) were dissolved in 2-methoxyethanol (2 mL) and heated at 100° C. for 48 hours. After cooling, the reaction was diluted with 10% Aqueous citric acid solution and the solids were collected by filtration. The solids were washed with water and Et2O and dried to afford 5-(2-m-tolylamino-pyrimidin-4-yl)thiophene-2-carboxylic acid (149 mg, 53.8%) as a yellow solid. MS: m/z 312 (M+H+).
