실험 절차

Methyl 2-chloro-4-methyl-6-(m-tolylamino)pyrimidine-5-carboxylate (0.4 g, 1.371 mmol), tert-butyl prop-2-ynylcarbamate (0.426 g, 2.74 mmol), tetrakis(triphenylphosphine)palladium (0.032 g, 0.027 mmol), and copper (I) iodide (0.026 g, 0.137 mmol) was dispersed in DMA (5 mL). Triethylamine (0.382 mL, 2.74 mmol) was added and the mixture was degassed with nitrogen for 5 min. The reaction mixture was placed in a sealed tube and heated at 90° C. for 4 h, after which it was filtered through a pad of Celite, which was rinsed with MeOH. The filtrate was purified via reverse phase preparative HPLC and the fractions were concentrated in vacuo to give the title compound as a brown oil (0.190 g, 34%). [M+H] calc'd for C22H26N4O4, 411; found, 411.
