Procedure

4-Chloro-7-(3-chloro-pyridin-2-yl)-5,6,7,8-tetrahydro-pyrido[3,4-d]pyrimidine (100 mg, 0.35 mmol) was dissolved in acetonitrile (2 mL). To the mixture was added 4-flouroaniline (0.067 mL, 0.71 mmol), sodium iodide (80 mg, 0.53 mmol) and HI (47%, 0.2 mL). The mixture was heated in a sealed tube at 130° C. for 10 minutes in a Personal Chemistry Microwave (Smith Creator). The solvent was removed under vacuum and the resulting orange residue dissolved in ethyl acetate and washed with saturated sodium bicarbonate and brine. The organic layer was dried over sodium sulphate, filtered and evaporated. The residue was purified by flash chromatography over silica gel using a 0-100% ethyl acetate-hexane gradient to give the product as an off white solid (53 mg).
