Procedure

A mixture of 4-(3-chloro-4-fluoro-phenylamino)-5,7-dihydro-pyrrolo[2,3-d]pyrimidin-6-one (6.3 mg, 0.0226 mmol), 3-(5-formyl-2,4-dimethyl-1H-pyrrol-3-yl)-propionic acid (4.9 mg, 0.0249 mmol) and piperidine (4 drops) in ethanol (1 mL) was stirred at room temperature for 24 hours. The reaction was concentrated and purified (reversed phase HPLC) to give 5.2 mg (51%) of the title compound. MS 456.4 [M++1].
