실험 절차

To a solution of (2S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-(4-chlorophenyl)-2-methylmorpholino)-5-methylbenzo[d]thiazol-6-yl)acetate (63.7 mg, 0.101 mmol) in CH3OH/THF (1:1, 4 mL) was added NaOH (2N, 1 mL, 2 mmol), the resulting mixture was heated at 50° C. for 14 hr. The mixture was evaporated to a small volume, acidified to pH 3 and taken into partitioned between CH2Cl2 and brine. The organic layer was separated, dried (Na2SO4), filtered and evaporated to dryness. The residue was purified on CombiFlash (50% EtOAc/Hex) to give (2S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-(4-chlorophenyl)-2-methylmorpholino)-5-methylbenzo[d]thiazol-6-yl)acetic acid. LCMS-ESI+: calc'd for C31H32Cl2N2O4S: 599.2, 601.2 (M+H+); found: 599.2, 601.2 (M+H+). 1H-NMR: 400 MHz, (CD3OD) δ: 7.62 (m, 1H), 7.44-7.53 (m, 5H), 7.32 (m, 3H), 5.13 (s, 1H), 4.31 (t, J=14.4 Hz, 1H), 3.81 (m, 1H), 3.62 (m, 1H), 3.44-3.53 (m, 3H), 2.50 (s, 3H), 1.46 (s, 3H), 0.95 (s, 9H).
