실험 절차

A mixture of 2-((3-(1-carbamoyl-7-(2-methoxyethoxy)-9H-pyrido[3,4-b]indol-4-yl)-2-methylphenylamino)methyl)-5-chlorobenzoic acid, TFA (38 mg, 0.056 mmol), N,N-diisopropylamine (0.015 mL, 0.085 mmol), BOP (32.5 mg, 0.073 mmol), and N-methylmorpholine (0.024 mL, 0.220 mmol) in DMF (4 mL) was heated at 45° C. for 1 hr. The mixture was diluted with ethyl acetate (60 mL), washed sequentially with water (3×25 mL) and brine (25 mL), and dried over anhydrous MgSO4. After the solvent was removed under vacuum, the residue was purified by prep. Reverse phase HPLC. The correct fraction was concentrated under vacuum, basified with saturated NaHCO3 solution, and extracted with CH2Cl2 (3×30 mL). The combined extract was washed with brine (30 mL) and dried over anhydrous MgSO4. Removal of solvent under vacuum provided the desired product (21.7 mg, 0.039 mmol, 68.2% yield) as a yellow solid. LCMS (M+H)+=541.33. 1H NMR (500 MHz, DMSO-d6) δ: 11.66 (s, 1H), 8.30 (s, 1H), 8.20 (s, 1H), 7.82 (s, 1H), 7.77-7.73 (m, 3H), 7.67 (m, 1H), 7.54 (m, 1H), 7.45 (m, 1H), 7.36 (d, J=2.2 Hz, 1H), 7.14 (d, J=8.9 Hz, 1H), 6.71 (dd, J1=8.7 Hz, J2=2.4 Hz, 1H), 5.04 (d, J=17.5 Hz, 1H), 4.95 (d, J=17.5 Hz, 1H), 4.16 (m, 2H), 3.72 (m, 2H), 3.34 (s, 3H), 1.87 (s, 3H).
