To a solution of (Z)-7-chloro-5-(4-methoxyphenyl)-3-(2-methylbenzyl)-1H-benzo[e][1,4]diazepin-2(3H)-one precursor (0.6 g, 1.4 mmol) in CH2Br2 (20 mL) was added EtSH (7 mL) and then A1Br3 (1.7 g, 6.3 mmol, 4.5 eq). The resulting mixture was stirred overnight and then treated with ice (20 g) and after one hour filtered. The resulting solid was triturated with 50% DCM/heptane and then vacuum dried to give 445 mg (yield of 80%) of (Z)-7-chloro-5-(4-hydroxyphenyl)-3-(2-methylbenzyl)-1H-benzo[e][1,4]diazepin-2(3H)-one as a light yellow solid. 1H NMR (300 MHz, DMSO-d6) δ 2.31 (s, 3H), 3.25-3.45 (m, 2H), 3.73 (dd, 1H), 6.80 (d, 2H), 7.02-7.18 (m, 3H), 7.2-7.3 (m, 5H), 7.64 (dd, 1H), 10.0 (br s, 1H), 10.7 (br s, 1H).
