1-[2-(4-bromophenyl)azetidin-1-yl]ethanone

Conditions: temp:110.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of methyl 6-chloro-5-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-1H-indole-3-carboxylate (100 mg, 0.311 mmol), 1-[2-(4-bromophenyl)azetidin-1-yl]ethanone (100 mg, 0.373 mmol), 2.0M aqueous potassium carbonate (0.50 mL, 1.0 mmol), and Pd(dppf)Cl2 (30 mg, 0.03 mmol) in toluene/ethanol (1.44 mL/0.48 mL) was stirred at 110° C. for 2.5 hours. The mixture was poured into ethyl acetate and washed with water. The organic phase was dried over sodium sulfate, filtered, and concentrated to give a residue. This was purified by preparative TLC to give the title compound (40 mg, 51% yield) as a white solid. washed with water The organic phase was dried over sodium sulfate filtered concentrated to give a residue This was purified by preparative TLC

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a mixture of 2-(4-bromophenyl)azetidine (200 mg, 0.808 mmol) and triethylamine (98 mg, 0.97 mmol) in anhydrous dichloromethane (6 mL) was added acetic anhydride (200 mg, 0.97 mmol). The mixture was stirred at rt for 5 hours. The mixture was poured into ethyl acetate and washed with water. The organic phase was dried over sodium sulfate, filtered, and concentrated in vacuo to give the title compound (100 mg, 49% yield) as a yellow oil that was taken on without further purification. washed with water The organic phase was dried over sodium sulfate filtered concentrated in vacuo
