Versuchsvorschrift

A mixture of 4-chloro-1H-pyrrolo[2,3-b]pyridine (0.050 g, 0.00033 mol) and 4-bromo-3-methyl-1H-pyrazole (0.10 g, 0.00066 mol) was heated at 130° C. overnight. The reaction mixture then was subjected to column chromatography (eluting with 5% MeOH/DCM, 0.5% NH4OH, on silica gel) to give 80 mg pale yellow solid which was triturated with MeOH (1.5 mL) to yield the product as a pale yellow solid (44 mg, 44% yield).
