Procedure

To a stirred and cooled (dry ice-acetone bath) solution of (Z)-3-(3-bromobenzyl)-7-chloro-5-(4-methoxyphenyl)-1-methyl-1H-benzo[e][1,4]diazepin-2(3H)-one (1.21 g, 2.5 mmol) and PdCl2(dppf) [0.22 g] in dry THF (10 mL) was added 1 M Et2Zn (9.3 mL, 10 mmol, 4 eq). After warming to RT, the reaction mixture was stirred at 50° C. until HPLC indicated reaction to be complete. After aqueous workup, chromatography gave 0.95 g (yield of 88%) of title product. 1H NMR (300 MHz, CDCl3) δ 1.22 (t, 3H), 2.62 (q, 2H), 3.55 (d, 2H), 3.70 (t, 1H), 3.84 (s, 3H), 6.89 (d, 2H), 7.03 (m, 1H), 7.1-7.3 (m, 5H), 7.4-7.55 (m, 3H).
