실험 절차

A mixture of 1-[7-(2-chlorophenyl)-8-iodo-2-methylpyrazolo[1,5-a][1,3,5]triazin-4-yl]4-ethylaminopiperidine-4-carboxylic acid amide (I-1A-1i; 20 mg, 0.037 mmol) and 4-fluorophenylboronic acid (7.8 mg, 0.056 mmol) in ethanol (1.3 ml), toluene (1.3 ml) and 2M aqueous Na2CO3 (0.3 ml) was degassed (3×) by pulling a vacuum followed by refilling with nitrogen gas. Tetrakis(triphenylphosphine)palladium (6 mg, 0.005 mmol) was added and the mixture was heated at 80° C. for 5 hours. After cooling to room temperature, the mixture was extracted from water with ethyl acetate, the combined organic layers were washed with brine, dried (MgSO4), filtered through a 0.45 μm filter disk, and then concentrated, in vacuo, to afford the crude product (50 mg). Purification on a Chromatotron using 0-3% methanol in methylene chloride as eluant afforded a light yellow oil, which was crystallized from diethyl ether, and dried, in vacuo, to afford 1A-1 (11 mg, 58%) as a colorless solid: +ESI MS (M+1) 508.4; 1H NMR (400 MHz, CD3OD) δ 7.46-7.34 (m, 4H), 7.32 (dd, J=8.7, 5.4 Hz, 2H), 6.96 (t, J=8.7 Hz), 4.70-4.58 (br m, 2H), 4.40-4.25 (br m, 2H), 2.51 (q, J=7.1 Hz, 2H), 2.46 (s, 3H), 2.20-2.12 (br m, 2H), 1.83-1.75 (m, 2H), 1.10 (t, J=7.1 Hz, 3H).
