Procedure

A solution of Pd(OAc)2 (4.0 mg, 0.017 mmol), and BINAP (10.5 mg, 0.017 mmol) in toluene (5 mL) was stirred at RT under N2 for 10 min, and then transferred to a mixture of 9-iodo-2-(3-methoxyphenyl)-7,8-dihydro-[1,4]diazepino[7,1-a]isoquinolin-5(4H)-one (Example 30) (150 mg, 0.34 mmol), morpholine (35 μL, 0.41 mmol) and Cs2CO3 (550 mg, 1.69 mmol) in toluene (5 mL). The reaction was stirred at RT under N2 for 5 min, and then heated to reflux for 24 h. The mixture was allowed to cool to RT, and then filtered and concentrated in vacuo. The crude product was purified by flash chromatography (SiO2, hexane to hexane/AcOEt 1:1) and the brown solid obtained was recrystallized from hexane to give the title compound (83 mg) as a beige solid. UPLC-MS: MS 404.5 (M+H+); UPLC rt 1.09 min. 1H NMR (400 MHz, CHLOROFORM-d): δ ppm 2.84-3.03 (m, 6 H); 3.76-3.95 (m, 6 H); 3.87 (s, 3H); 4.51 (br. s., 2 H); 6.92 (s, 1 H); 7.00 (dd, J=8.21, 2.74 Hz, 1 H); 7.14 (d, J=7.82 Hz, 1 H); 7.28-7.51 (m, 5 H).
