Sodium Chlorite → HCID 89662736, compound

Participants

Reaction Steps

A solution of sodium chlorite (214 mg; 2.36 mmol; 5.5 eq.) and sodium dihydrogenphosphate (186 mg; 1.55 mmol; 3.6 eq.) in water (2 mL) was added dropwise to a mixture of 4-(2-formyl-phenyl)-7-trifluoromethyl-[1,4]diazepane-1-carboxylic acid tert-butyl ester (160 mg; 0.43 mmol; 1 eq.) in 1,4-dioxane (2 mL). The reaction mixture was stirred at room temperature for 1 hour and the 1,4-dioxane concentrated in vacuo. The aqueous solution was diluted with water, the pH made acidic with 0.1M HCl and extracted with EA (2×). The combined organic layer was washed with brine, dried over magnesium sulfate and concentrated in vacuo to afford the title compound (140 mg, 84%) as a yellow solid. UPLC/MS: (MS+) 389.2 ([M+H]+).
