실험 절차

To a solution of 4-methoxy-2-(3-methyl-1-tosyl-1H-indol-4-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine, prepared as described in Example 17, (300 mg, 0.67 mmol) in toluene (3 mL), in a 2-5 mL microwave vial, was added methyl 4-methyl-3-oxopentanoate (0.28 mL, 2 mmol) followed by DMAP (25 mg, 0.2 mmol). The reaction vessel was then sealed and heated via microwave irradiation at 150° C. for 35 min. The reaction mixture was then cooled to room temperature and diluted with dichloromethane and water. The layers were separated and the organic layer was dried by passing through a phase separator and then concentrated. The resulting residue was purified via silica gel flash chromatography (45-90% ethyl acetate/heptanes) to furnish 1-(4-methoxy-2-(3-methyl-1-tosyl-1H-indol-4-yl)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)-4-methylpentane-1,3-dione. MS (ESI+) m/z 561.3 (M+H)+.
