Reaction Steps

525 mg of ethyl 4-bromobutyrate were added to a solution of 574 mg of p-[2-[[(RS)-2-hydroxy-3-phenoxypropyl]-amino]ethyl]phenol and 300 mg of potassium t-butylate in 10 ml of dimethylsulfoxide and the mixture was stirred at room temperature under argon for 6 hours. The solvent was evaporated in vacuo and the residue was chromatographed on 75 g of silica gel. Utilizing chloroform/n-propanol/saturate ammonia (500:10:1), there were obtained 600 mg of pure, amorphous ethyl 4-[p-[2-[[(RS)-2-hydroxy-3-phenoxypropyl]amino]ethyl]phenoxy]butyrate, ε221 =17510.
