Reaction Steps
[4-(6-Chloro-5-cyano-pyrazin-2-yl)-phenyl]carbamic acid tert-butyl ester (1.0 g) was suspended in a mixture of 10 ml iPrOH and 10 ml 35% hydrazine in water at RT and heated to 120° C. by microwave irradiation for 70 min under stirring in a sealed vessel. The reaction mixture was left to cool to RT, and the precipitate was filtered off and washed with water to afford [4-(3-amino-1H-pyrazolo[3,4-b]pyrazin-6-yl)-phenyl]-carbamic acid tert-butyl ester as a yellow solid after drying under vacuum. Yield: 815 mg (83%).
