Participants

Reaction Steps

A mixture of Example 204A (150 mg, 0.52 mmol), pyridin-2 (1H)-one (96 mg, 1.0 mmol), PPh3 (180 mg, 0.68 mmol) and di-tert-butyl azodicarboxylate (160 mg, 0.68 mmol) in 10 mL of THF was stirred overnight. The reaction mixture was purified by flash column chromatography on silica gel with 7:3 hexanes/ethyl acetate to provide 72 mg of the desired product. The column was then washed with 100:3:1 EtOAc/MeOH/NH4OH to give 79 mg of 3-chloro-8-[2-(2-oxo-2H-pyridin-1-yl)-ethyl]-5,10-dihydro-dibenzo[b,e][1,4]diazepin-11-one. MS (DCI) m/e 366 (M+H)+; 1H NMR (500 MHz, DMSO-d6) δ 9.83 (s, 1H), 8.13-8.14 (m, 1H), 7.97 (s, 1H), 7.65-7.68 (m, 2H), 7.05 (d, J=1.84 Hz, 1H), 6.89-6.95 (m, 5H), 6.76 (d, J=8.42 Hz, 1H), 4.38 (t, J=6.86 Hz, 2H), 2.99 (t, J=6.86 Hz, 2H).
