실험 절차

To a solution of 4-(phenethylthio)-1H-pyrrole-2-carboxylic acid (25.0 mg, 0.101 mmol) and 1-(4-amino-2-methoxyphenoxy)-2-methylpropan-2-ol (21.4 mg, 0.101 mmol) in dichloroethane (0.880 mL) was added EDC (38.8 mg, 0.202 mmol) and HOBT (30.9 mg, 0.202 mmol) and the reaction was allowed to stir at rt for 16 h. The reaction mixture was diluted with EtOAc (15 mL), washed with sat. NaHCO3 (3×20 mL), water, brine, dried over anhydrous Na2SO4, concentrated and purified by preparative HPLC: PHENOMENEX® Luna AXIA 5μ C18 21.2×100 mm, 15 min gradient, 10% MeOH/90% H2O/0.1% TFA to 90% MeOH/10% H2O/0.1% TFA, 5 min hold; 20 mL/min, UV detection at 220 nm, 10.739 min retention time to afford 21.3 mg of the title compound as brown solid: 1H NMR (500 MHz, CDCl3) δ 1.34 (s, 6 H), 2.85-2.97 (m, 4 H), 3.81 (s, 2 H), 3.85 (s, 3 H), 6.67 (br. s, 1 H), 6.88 (d, J=8.8 Hz, 1 H), 6.95 (dd, J=8.8, 2.2 Hz, 1 H), 7.02 (s, 1 H), 7.15-7.23 (m, 3 H), 7.24-7.32 (m, 2 H), 7.37 (s, 1 H), 7.55 (d, J=3.8 Hz, 1 H), 9.83 (br. s, 1 H); HPLC a) column: PHENOMENEX® Luna 5μ 4.6×50 mm, 4 min gradient, 10% MeOH/90% H2O/0.1% H3PO4 to 90% MeOH/10% H2O/0.1% H3PO4; 1 min hold, 4 mL/min UV detection at 220 nm, 3.650 min retention time, (>98%); HPLC b) column: PHENOMENEX® Luna C18 4.6×50 mm, 4 min gradient, 10% MeOH/90% H2O/0.1% TFA to 90% MeOH/10% H2O/0.1% TFA, 1 min hold; 4 mL/min, UV detection at 220 nm, 3.660 min retention time; MS (ES) 441 [M+H]+.
