Methylamine → Tert-butyl 3-(methylamino)propanoate

Participants

Reaction Steps

A 33% solution of methylamine in EtOH (62 ml) is cooled to 0°. A solution of tert-butyl acrylate (12.8 g) in EtOH (50 ml) is added dropwise over 2.5 hours. This mixture is allowed to reach room temperature over night. All volatiles are removed under reduced pressure and the residue chromatographed on silicagel using first EtOAc and then EtOAc/MeOH 1:1 as eluent. 7.81 g of a slightly yellow oil are obtained. TLC (silicagel, EtOAc/MeOH 1:1): rf 0.13.
