Procedure

A mixture of 181 mg (0.40 mmol) of diethyl 2-(2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-9-yl)malonate and 0.314 mL (10.0 mmol) of hydrazine in 4.0 ml of Ethanol was heated at 75° C. for 18 hours. The mixture was concentrated, the residue triturated with acetic acid. A precipitate was filtered off, washed with acetic acid, ethyl ether and recrystallized from ethyl ether/ethanol mixture to give 360. Yield 59 mg (37.5%). M/z 394.1, calc. 393.15. 1H NMR (400 MHz, DMSO) δ 10.20 (s, 2H), 8.29 (d, J=8.6, 1H), 7.89 (d, J=12.9, 2H), 7.70 (d, J=8.5, 1H), 7.63 (s, 1H), 5.93 (dt, J=13.1, 6.7, 1H), 4.48 (d, J=7.2, 4H), 1.49 (d, J=6.6, 6H)
