A mixture of (3,5-bis-trifluoromethyl-benzyl)-(6-chloro-1,3-dimethyl-1H-pyrazolo[3,4-b]pyridin-5-ylmethyl)-(2-methyl-2H-tetrazol-5-yl)-amine (0.5 g, 0.9 mmol), potassium-tert-butoxide butoxide (0.43 g, 3 mmol), cyclopropylmethyl amine (0.275 g, 3 mmol), and Pd(OAc)2 (0.01 g, 0.004 mmol), BINAP (0.03 g,0.04 mmol) was prepared in a 10 mL pressure vial. The pressure vial was placed in the focused microwave oven (CEM Discovery) and irradiated for 20 min at 110° C. by using 250 Watt microwave power. After this mixture was cooled to RT, ethyl acetate (100 mL) was added to the vial. The organic layer was washed with water (3×100 mL) and dried and concentrated. The resultant oil was purified by column chromatography using silica gel (230-400 mesh) and eluting the column with 10% ethyl acetate in hexane afforded a colorless solid (0.485 g, yield: 90%).
