Reaction Steps

7-(7H-Pyrrolo[2,3-d]pyrimidin-4-yl)-4,7-diaza-spiro[2.5]octane-4-sulfonic acid amide (intermediate 1) (0.46 mmol) was suspended en dry toluene (5 ml), added 4-methoxybenzaldehyde (0.46 mmol) and stirred at reflux for 48 h. The obtained reaction mixture was concentrated in vacuo on silica. The product was purified by flash chromatography on silica using EtOAc in heptane as eluent.
