DL-Homoserine → Methyl homoserinate hydrochloride

참여 물질

반응 단계

A suspension of DL-homoserine (1.00 g, 8.39 mmol) in methanol (40 mL) was placed in an ice bath. Trimethylsilyl chloride (2.34 mL, 18.5 mmol) was added dropwise via syringe. The reaction mixture gradually became homogenous and was further stirred at rt for 14 h, concentrated by rotary evaporation, and further dried under high vacuum. The crude oil thus obtained was used for the next step without further purification. 1H NMR (300 MHz, CD3OD) δ 2.00-2.24 (m, 2H), 3.70-3.80 (m, 2H), 3.85 (s, 3H), 4.12-4.22 (m, 1H). m/z (ESI) 134 [C5H11NO3+H]+.
