실험 절차

(R)-4-((S)-1-(tert-butoxy)ethyl)-3-(2-(((S)-1-(1-(4-chloro-3-(trifluoromethoxy)phenyl)piperidin-4-yl)ethyl)amino)-5-fluoropyrimidin-4-yl)oxazolidin-2-one (34 mg, 0.058 mmole) was dissolved in DCM (1 mL), TFA (1 mL) was added. The reaction solution was stirred for 2 hour at room temperature and was concentrated by rotary evaporation. The resulting residue was dissolved in DCM (2 mL) and water 2 mL) and the pH was adjusted to ˜9 with NH4OH. The DCM layer was separated and concentrated by rotary evaporation to afford 28 mg of the title product as a yellow oil (ratio of two peaks with same MS: 96/4% by LC-MS). (400 MHz, CD2Cl2) δ 8.22 (d, J=2.27 Hz, 1H), 7.31 (d, J=8.85 Hz, 1H), 6.88-6.79 (m, 2H), 5.12 (br s, 1H), 4.61-4.50 (m, 2H), 4.46-4.37 (m, 1H), 4.26-4.15 (m, 1H), 3.93 (br s, 1H), 3.77-3.68 (m, 2H), 3.20 (br s, 1H), 2.79-2.67 (m, 2H), 1.96-1.78 (m, 2H), 1.70-1.58 (m, 1H), 1.55-1.28 (m, 2H), 1.23 (d, J=6.63 Hz, 3H), 1.19 (d, J=7.19 Hz, 3H), HRMS(C) tR=4.47 min; MS m/z 548.1689 (M+H)+
