General procedure: A mixture of 2,4-dichloro-7,7-dimethyl-5,7-dihydrofuro[3,4-d]pyrimidine7 (257mg, 1.173 mmol), 1H-pyrazolo[4,3-c]pyridin-3-amine (291 mg, 1.735 mmol), N,N-diisopropylethylamine (0.40 mL, 2.3 mmol) and N,N-dimethylformamide (4.0 mL) was heated at 70 C for 2 hours. The reaction mixture was diluted with ethyl acetate, washed with water (2x) and brine, dried over magnesium sulfate, filtered, and evaporated in vacuo. The crude product was purified via flash chromatography on silica gel (24 silica, solvent gradient: 0-100% ethyl acetate in dichloromethane followed by 10% methanol indichloromethane) to yield 176.7 mg of the title compound.
