実験手順

A mixture of 4-(6-chloro-5-methoxy-pyrimidin-4-yloxy)-piperidine-1-carboxylic acid isopropyl ester (570 mg, 1.73 mmol), 6-methanesulfonyl-4-methyl-pyridin-3-ylamine (272 mg, 1.46 mmol), palladium acetate (27.3 mg, 0.122 mmol), 2,8,9-triisobutyl-2,5,8,9-tetraaza-1-phospha-bicyclo[3.3.3]undecane (87 μl, 0.245 mmol), and sodium 2-methylpropan-2-olate (249 mg, 2.59 mmol) in 4.5 mL dioxane was heated under microwave irradiation at 120° C. After 4 h, mixture was purified by HPLC; fractions containing pure product were collected and concentrated. Residue was treated with 4M HCl in dioxane, concentrated, and dried under high vacuum to give 4-[6-(6-methanesulfonyl-4-methyl-pyridin-3-ylamino)-5-methoxy-pyrimidin-4-yloxy]-piperidine-1-carboxylic acid isopropyl ester as a white solid (HCl salt, 261 mg, 29%). 1HNMR (MeOH-d4, 400 MHz) δ 1.23-1.24 (d, J=6.2 Hz, 6H), 1.75-1.81 (m, 2H), 1.97-2.04 (m, 2H), 2.40 (s, 3H), 3.17 (s, 3H), 3.39-3.46 (m, 2H), 3.71-3.77 (m, 2H), 3.92 (s, 3H), 4.82-4.88 (m, 1H), 5.35-5.40 (m, 1H), 7.99 (s, 1H), 7.99 (s, 1H), 8.96 (s, 1H). Exact mass calculated for C21H29N5O6S 479.18 found 480.4 (MH+).
