Reaction Steps

3-Ethoxy-4-(pyridine-3-yl-amino)-3-cyclobutene-1,2-dione (164 mg, 0.75 mmol) prepared according to example 1A and 2-(1-benzylpiperidin-4-yl)-ethylamine (196 mg, 0.90 mmol) in EtOH (4 mL) were stirred and heated to 150° C. in a sealed vessel in a microwave synthesizer for 3 min. After cooling to r.t. the precipitate was filtered off and washed with EtOH (3×3 mL) and dried in vacuo.
