Methyl iodide → Methyl 1-(diphenylmethyl)azetidine-3-carboxylate

Participants

Reaction Steps

Potassium carbonate (6.53 g) and iodomethane (0.976 ml) were added to a solution of 1-benzhydrylazetidine-3-carboxylic acid (4.20 g) in N,N-dimethylformamide (45 ml), followed by stirring at room temperature for 20.5 hours. The reaction mixture was poured into ice water, and extracted with ethyl acetate. The organic layer was washed with brine, and dried over anhydrous sodium sulfate. The solvent was distilled off, and the residue was purified by silica gel column chromatography (eluent; heptane:ethyl acetate=5:1, then 3:1). The fractions containing the target compound were concentrated to give the title compound (3.57 g, 80.8%) as yellow crystals.
