실험 절차

1,1-Dimethylethyl (2S)-4-({4-[{[6-(3-fluorophenyl)-3-pyridinyl]carbonyl}(methyl)amino]phenyl}methyl)-2-methyl-1-piperazinecarboxylate (D60) (0.127 g, 0.245 mmol) was stirred in DCM (10 mL) and TFA (2.5 mL) was added drop-wise. The reaction mixture was stirred for ˜1 h, then concentrated in vacuo and re-diluted with DCM and water. The separated aqueous layer was basified to pH14 with concentrated NaOH solution, then extracted with DCM which was dried (Na2SO4) and concentrated to yield the title compound as a yellow oil (0.091 g). δH (CDCl3, 400 MHz) 8.52 (1H, d), 7.75 (1H, dd), 7.67 (2H, m), 7.54 (1H, d), 7.40 (1H, m), 7.25 (2H, d), 7.09 (1H, m), 7.03 (2H, d), 3.53 (3H, s), 3.41 (2H, s), 2.83 (3H, m), 2.66 (2H, d), 1.96 (1H, td), 1.62 (1H, m), 1.55 (br.s), 0.97 (3H, d), NH not observed. MS (ES): MH+ 419.2.
