Reaction Steps

9-ethynyl-2-(3-methoxyphenyl)-7,8-dihydro-[1,4]diazepino[7,1-a]isoquinolin-5(4H)-one. 40-2. A solution of 37-1 (700 mg, 1.69 mmol) in MeOH (20 mL) was treated with K2CO3 (467 mg, 3.38 mmol) and the mixture was stirred at RT for 18 h. The mixture was concentrated in vacuo, and the residue taken up in AcOEt and washed with H2O. The organic layer was then dried over Na2SO4, filtered and concentrated in vacuo. The crude product was re-crystallized from heptane/AcOEt to provide the title compound (410 mg) as brown crystals. UPLC-MS: MS 343.3 (M+H+); UPLC rt 1.03 min.
