Participants

Reaction Steps

A solution of sodium chlorite (1.37 g; 15.10 mmol; 5.5 eq.) and sodium dihydrogenphosphate (1.19 g; 9.89 mmol; 3.6 eq.) in water (8 mL) was added dropwise to a mixture of 2-methyl-2-butene (2.7 mL) and 3-(2-formyl-phenoxymethyl)-azetidine-1-carboxylic acid tert-butyl ester (800 mg; 2.75 mmol; 1 eq.) in 1,4-dioxane (8 mL) and the resulting mixture was stirred at room temperature for 1 hour. The 1,4-dioxane was evaporated in vacuo, water was added and the pH made acidic with 1M HCl. The precipitate was filtered off to afford the title compound (827 mg, 98%) as a white solid. HPLC (max plot) 100%; Rt 3.58 min. UPLC/MS: (MS−) 306.4 ([M−H]−).
