Reaction Steps

4-Chloro-7H-pyrrolo[2,3-d]pyrimidin-2-amine (0.5 g, 2 96 mmol) and 2-furoic acid hydrazide (0.76 g, 6.0 mmol) are taken into 30 mL of n-butanol. The mixture is stirred at 120° C. under N2 for 2 h. The solvent is evaporated in vacuum and the residue is triturated with water and filtered to afford compound N′-(2-amino-7H-pyrrolo[2,3-d]pyrimidin-4-yl)furan-2-carbohydrazide: LC/MS (M+1=259.32). This material is used in the next step without further purification.
