実験手順

A solution of 22.7 g (0.23 mole) of phosgene in 200 ml of methylene chloride was treated with 29 g (0.23 mole) of potassium carbonate, stirred for 30 min, then 75.4 g (0.19 mole) of 3-(3-bromophenoxy)-1-diphenylmethylazetidine in 150 ml of methylene chloride was added dropwise. After stirring for 5 hr, the inorganic salts were removed by filtration and the filtrate was washed with water to destroy excess phosgene. Concentration (after drying) in vacuo yielded 96.85 g of oily residue. Trituration of the residue with isopropyl ether yielded 42 g of crude tan-gray product. A sample for analysis was recrystallized from isopropyl ether, m.p. 87°-88° C.
