ethyl N,N-dibutyl-beta-alaninate

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Ethyl 3-bromopropionate (18.0 g; 0.10 mol) was added carefully to di-n-butylamine (25.8 g; 0.20 mol), followed by stirring for 2 hours. Then diethyl ether (200 ml) and pentane (200 ml) were added. The precipitate was filtered off, the filtrate was evaporated and the residue was distilled at sub-atmospheric pressure. The yield was 7.0 g (31%). The precipitate was filtered off the filtrate was evaporated the residue was distilled at sub-atmospheric pressure
