Versuchsvorschrift

To 6-bromo-2-(tetrahydro-2H-pyran-2-yl)-2H-indazol-4-amine (1.47 g) in DCM (20 ml) was added pyridine (1 ml). The reaction mixture was stirred for 5 minutes at room temperature before 2-(chloromethyl)-1,3-thiazole-4-carbonyl chloride (1.21 g) in DCM (20 ml) was added dropwise over 10 minutes. The reaction mixture was stirred at room temperature for 18 hours. Saturated sodium bicarbonate solution (40 ml) was added and the reaction was stirred vigorously before the organic layer was separated using a hydrophobic frit. The aqueous layer was extracted with further DCM and the combined organic layers were evaporated to dryness. The residual solid was dried on a high vacuum line before triturating with cyclohexane to give the title compound (1.52 g).
