HCID 232160883-(Benzyl-methyl-amino)-butyric acid methyl esterYield 110.4%

Procedure

Benzyl-methyl-amine (20 g, 165 mmol, 1.0 equiv) was added neat to methyl crotonate (19.8 g, 198 mmol, 1.2 equiv). The resulting solution was stirred at room temperature for 72 h. The excess crotonic ester was removed in vacuo to yield the desired product (40.3 g, ˜100%) which was used without further purification; MS, m/z 222=M+1.

Workup

  1. customThe excess crotonic ester was removed in vacuo
