Dichloromethane → 3(R,S)Ethoxycarbonylamino-1,2,3,4-tetrahydroquinoline

Participants

Reaction Steps

10 ml of a 10% sodium hydroxide solution and 0.34 ml of ethyl chloroformate are added in succession to a solution of 0.5 g of 3(R,S)-amino-1,2,3,4-tetrahydroquinoline in 6 ml of toluene, while stirring vigorously, and when the addition has ended, the mixture is stirred for a further 5 min. Customary working up and chromatography of the crude product over 25 g of silica gel with methylene chloride as the mobile phase gives the title compound: Rf (P)=0.78; MS: M+ =220.
