実験手順

A solution of 1.2 g (3.3 millimoles) of 1-(2,4-dimethoxy-benzyl)-4-iodomethyl-2-azetidinone and 5 ml of dimethyl formamide is stirred with 0.35 g (7 millimoles) of sodium cyanide at room temperature for 48 hours. The solution is poured onto 30 ml of water and extracted five times with 20 ml of ether each. The etheral solution is dried over anhydrous magnesium sulfate, filtered and the filtrate is evaporated in vacuo. Thus 0.6 g of 4-cyanomethyl-1-(2,4-dimethoxy-benzyl)-2-azetidinone are obtained. Yield: 70%.
