Methanesulfonic Acid → HCID 85923180, compound

Participants

Reaction Steps

5.0 g (43.4 mmol) of methyl 3-aminocrotonate, 70 ml of anhydrous methanol, 1.0 equivalent of methanesulfonic acid and 0.22 g of Pt/C catalyst (Heraeus K0129) were introduced into a 160 ml Parr autoclave. The hydrogenation was carried out for 2 hours at approximately 20° C. under 5-10 bar of hydrogen. The catalyst was then filtered off and the solvent was completely removed by distillation on a rotary evaporator. 6.2 g of pure methyl (RS)-3-aminobutyrate methanesulfonate were obtained as an oil.
