Reaction Steps

To a solution of [2-chloro-5-((Z)-2-ethoxy-vinyl)-pyrimidin-4-yl]-(1-ethylpropyl)-amine (1.1 g, 4.07 mmol) in EtOH (8 mL) is added concentrated HCl (0.1 mL) at ambient temperature. The reaction mixture is sealed in a microwave reactor and heated at 100° C. for 10 min. After cooling to room temperature, the mixture is concentrated in vacuo to provide 2-chloro-7-(1-ethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidine. The crude product is used as it is. The crude product can be purified by flash chromatography (SiO2, EtOAc/Hexane 1:5).
