Versuchsvorschrift

A mixture of the 1C, 2.5 g of sodium hydroxide, 36 ml of ethanol and 24 ml of water was refluxed for 6 hours, then left to cool for 16 hours. The mixture then was poured into water, washed with ether and acidified to pH 5. The solvent was evaporated, the residue was taken up in methanol, the solution was filtered and the methanol was evaporated. The residue was dissolved in chloroform; the solution was washed with brine, dried and the solvent was evaporated, to give 1-benzhydryl-2-azetidine carboxylic acid (1D).
