실험 절차
To a microwave reaction vial was added tert-butyl {3-[(2-chloro-5-cyano-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)oxy]cyclobutyl}carbamate (508 mg, 1.0 mmol), 1-methyl-1H-pyrazol-4-amine (110 mg, 1.1 mmol), 1,4-dioxane (10 mL), Cs2CO3 (670 mg, 2.1 mmol, 2 mol eq), Xantphos (62 mg, 0.1 mmol) and Pd2(dba)3 (94 mg, 0.1 mmol). The reaction vial was flushed with nitrogen, capped, stirred and heated to 140° C. in a Biotage microwave reactor for 1 hr and 45 min. The reaction was diluted with EtOAc (120 mL) and water (20 mL). The organic layer was separated, washed with water (20 mL), brine (10 mL), and dried over Na2SO4. After concentrating the extract to dryness, the product was purified via flash chromatography eluting with a gradient of 0%-60% EtOAc in heptanes to afford the title compound (480 mg, 84 yield) as a light yellow solid. 1:1 cis:trans mixture: 1H NMR (400 MHz, DMSO-d6) δ ppm 9.42 (s, 1H) 8.11 (s, 1H) 7.96 (br. s., 1H) 7.49-7.60 (m, 1H) 7.20-7.46 (m, 1H) 5.53 (br. s., 2H) 4.11-5.13 (m, 1H) 3.82 (s, 3H) 3.56 (t, J=7.55 Hz, 2H) 2.83 (d, J=6.80 Hz, 1H) 2.39-2.48 (m, 2H) 2.02-2.16 (m, 1H) 1.39 (d, J=5.54 Hz, 9H) 0.84 (t, J=8.06 Hz, 2H) −0.12 (br. s., 9H). m/z (APCI+) for C26H38N8O4Si 555.1 (M+H)+.
