실험 절차

A mixture of 1-[trans-4-(tert-butyl-dimethyl-silanyloxy)-cyclohexyl]-7-chloro-3-(4-methoxy-phenyl)-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one (0.20 g, 0.40 mmol) (from Example 19a supra) and 4-amino-veratrole (80.0 mg, 0.52 mmol) (Aldrich) in 2-propanol (4 mL) was placed in a microwave reactor (SmithSynthesizer™). The reaction mixture was heated at 160° C. for 10 minutes. After cooling, it was concentrated under reduced pressure. The residue was purified by flash chromatography eluting with ethyl acetate-hexanes (3:7 then 2:3) to give 1-[trans-4-(tert-butyl-dimethyl-silanyloxy)-cyclohexyl]-3-(4-methoxy-phenyl)-7-(3,4-dimethoxy-phenylamino)-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one. (Yield 0.09 g, 36%).
