Acetyl chloride → tert-Butyl (1-acetylazetidin-3-yl)(methyl)carbamate

Participants

Reaction Steps

tert-Butyl N-(1-benzhydrylazetidin-3-yl)-N-methylcarbamate (I-149) (0.40 g, 1.13 mmol) was dissolved methanol (20 ml), then 20% palladium hydroxide-carbon (containing about 50% water, 20 g) was added, followed by stirring at room temperature under hydrogen atmosphere for 15 hours, and the catalyst was removed by filtration. The solvent was evaporated away under reduced pressure, the resulting residue was dissolved in dichloromethane (10 ml), and triethylamine (0.20 ml, 3.44 mmol) and acetyl chloride (90.0 μl, 26 mmol) were added.
