Participants

Reaction Steps

To a solution of 11-chlorodibenzo[b,f][1,4]thiazepine, prepared as described in the previous step, (2 g, crude) in dioxane (20 mL) was added Pd2(dba)3 (327 mg, 0.357 mmol), BINAP (225 mg, 0.357 mmol), triethylamine (6 mL, 42.9 mmol) and 2,2,2-trifluoro-N-((1-(2-(2-hydroxyethoxy)ethyl)piperazin-2-yl)methyl)acetamide, prepared as described as Step F, (2.4 g, crude). The resulting mixture was heated to reflux overnight under nitrogen atmosphere, filtered through CELITE™, and concentrated. The residue was purified by silica gel chromatography to provide the title compound. ESI-MS (M+1): 509 calc. for C24H27F3N4O3S 508.
