실험 절차

A mixture of 12.5 g of 3,4-dihydro-N-(phenylmethyl)-2H-1-benzopyran-2-methanamine, 9 g of 4-bromobutanenitrile, 200 ml of N,N-dimethylformamide and 10 ml of N,N-diethylethanamine was stirred for 72 hour at room temperature. The reaction mixture was evaporated and the residue was partitioned between 1,1'-oxybisethane and water. The organic layer was separated, dried, filtered and evaporated, yielding 11 g (68.7%) of (±)-4-[[(3,4-dihydro-2H-1-benzopyran-2-yl)methyl](phenylmethyl) amino]-butanenitrile (interm. 53).
