Yield: 29%
Reaction Conditions:
with hydrogenchloride in 1,4-dioxane;toluene at 115;
Steps:
1
(E) -Ethyl 3-aminobut-2-enoate (2.53 g, 19.6 mmol) in toluene (15 mL) was charged with 4N HCl (10 mL, 40 mmol) in dioxane. The mixture was stirred at 115°C overnight. The solution was cooled and the solid was filtered off washing with toluene. The filtrate was concentrated and the residue was purified by silica gel column chromatography (5% MeOH/EtOAc) to
