실험 절차

1,1-Dimethylethyl (2S)-2-methyl-4-{[4-(methylamino)phenyl]methyl}-1-piperazine-carboxylate (D3) (0.4 g, 1.254 mmol) was taken up in DCM (4 mL) under argon. 6-Chloro-3-pyridinecarbonyl chloride (0.243 g, 1.379 mmol) in DCM (4 mL) and triethylamine (0.348 mL, 2.508 mmol) were added. The mixture was stirred at room temperature overnight. The mixture was diluted with DCM and washed with water. The aqueous layer was extracted with DCM (×2) and the combined organics dried and concentrated to a pale yellow oil. The crude product was purified by column chromatography. Elution with a 0-50% EtOAc/petroleum ether gradient yielded the title compound as a white foam/gum (0.601 g). δH (CDCl3, 400 MHz) 8.21 (1H, d), 7.61 (1H, dd), 7.25 (2H, d), 7.16 (1H, d), 6.99 (2H, d), 4.18 (1H, br.s), 3.80 (1H, d), 3.50 (3H, s), 3.47 (1H, d), 3.34 (1H, d), 3.10 (1H, td), 2.70 (1H, d), 2.49 (1H, d), 2.10 (1H, dd), 2.00 (1H, m), 1.46 (9H, s), 1.20 (3H, d). MS (ES): MH+ 459.2.
