Embodiment 1
[0117]
[0118] (S)-2-(8-Chloro-2-(benzofuran-6-carbonyl)-2,3-dihydro-1H-pyrrole[3,2,1-ij]quinazoline-7-carboxamide base)-3-(3-(methylsulfonyl)phenyl)propionic acid
[0119] The specific reaction equation is as follows:
[0120]
[0121] Step A: Dimethyl 2-amino-5-chloroterephthalate (Compound 1-1)
[0122]To a vigorously stirred solution of dimethyl 2-aminoterephthalate (10 g, 48 mmol) in isopropanol (1.5 L) was added NCS (7.34 g, 55 mmol) over a period of 5 minutes at room temperature. After the addition was complete, the reaction mixture was heated to reflux for 48 hours. After cooling to room temperature, the solvent was concentrated and the residue was purified by flash chromatography eluting with 5% ethyl acetate in petroleum jelly to give the desired product (6.4 g, 55%) as a pale yellow crystalline solid. LCMS ESI (+) m / z: 244 (M+1). 1 H NMR (600MHz, CDCl3) δ7.92(s,1H),7.10(s,1H),5.71(brs,2H),3.92(s,3H),3.90(s,3H).
[0123] Step B: Dimethyl 2-amino-3-bromo-5...

[0150]
[0151] (S)-2-(8-Chloro-2-(1H-indole-6-carbonyl)-2,3-dihydro-1H-pyrrole[3,2,1-ij]quinazoline-7- Formamido)-3-(3-(methylsulfonyl)phenyl)propanoic acid
[0152] The title compound was prepared according to the procedure of Example 1, Steps M and N, using 1H-indole-6-carboxylic acid instead of compound benzofuran-6-carboxylic acid to give a white solid. LCMS ESI (+) m / z: 605 (M+1). 1 H NMR(600MHz,DMSO)δ12.89(brs,1H),11.39(s,1H),8.78(d,J=8.2Hz,1H),7.89(s,1H),7.79(d,J=7.8Hz ,1H),7.70(d,J=7.5Hz,1H),7.63(d,J=8.1Hz,1H),7.59(t,J=7.7Hz,1H),7.52(s,1H),7.53–7.46 (m,1H),7.46(s,1H),7.04(d,J=8.2Hz,1H),7.03–6.93(m,1H),6.52(s,1H),6.13(s,1H),5.99– 5.78(m,2H),5.14–4.95(m,2H),4.85–4.69(m,1H),3.30–3.26(m,1H),3.12(s,3H),3.10–3.03(m,1H).
Embodiment 3
[0154]
[0155] (S)-2-(8-chloro-2-(pyrazol[1,5-a]pyridine-2-carbonyl)-2,3-dihydro-1H-pyrrole[3,2,1-ij] Quinazoline-7-carboxamido)-3-(3-(methylsulfonyl)phenyl)propionic acid
[0156] The title compound was prepared according to the method of Steps M and N of Example 1, using pyrazol[1,5-a]pyridine-2-carboxylic acid instead of compound benzofuran-6-carboxylic acid to obtain a white solid. LCMS ESI (+) m / z: 606 (M+1). 1 H NMR (600MHz, DMSO) δ12.89(brs, 1H), 8.76(d, J=8.0Hz, 1H), 8.75(d, J=6.5Hz, 1H), 7.88(s, 1H), 7.79(d ,J=8.3Hz,1H),7.77(d,J=10.1Hz,1H),7.69(d,J=7.6Hz,1H),7.58(t,J=7.7Hz,1H),7.63–7.40(m ,1H),7.33(t,J=7.7Hz,1H),7.10–7.01(m,1H),7.15–6.92(m,1H),6.90(s,1H),6.30–6.18(m,1H), 6.17–6.06(m,1H),,6.06–5.93(m,1H),5.44–5.31(m,1H),5.23–5.08(m,1H),4.82–4.74(m,1H),3.32(dd, J=14.3,4.3Hz,1H),3.11(s,3H),3.05(dd,J=13.5,11.4Hz,1H).
