在冰浴条件下,于氮气保护下,将3 mL的氯化亚砜(SOCl2)缓慢滴加至35 mL甲醇中。随后,将反应混合物于室温下搅拌1小时。之后,分批加入1 g L-半胱氨酸盐酸盐一水合物(Cys·HCl·H2O)至上述溶液中。将混合溶液在室温下继续反应3小时,然后加热回流1小时。反应完成后,通过减压蒸馏除去挥发性组分及溶剂,所得残余物用甲醇-二氯甲烷(CH3OH-CH2Cl2)混合溶剂进行重结晶,得到0.84 g白色固体产物L-半胱氨酸甲酯盐酸盐,产率为85.9%。产物经红外光谱(IR, KBr压片)分析显示特征吸收峰:3040.4 cm-1(强,NH2伸缩振动),1709.7 cm-1(强,C=O伸缩振动),2580 cm-1(弱,SH伸缩振动)。核磁共振氢谱(1H NMR, D2O为溶剂,TMS为内标)数据如下:δ 4.453 (t, 1H, CH, J = 5.2 Hz), 3.871 (s, 3H, CH3), 3.164 (t, 2H, CH2, J = 6.4 Hz)。元素分析结果:计算值(C4H10NO2SCCl): C, 27.99%; H, 5.87%; N, 8.16%。实测值:C, 28.11%; H, 6.01%; N, 8.08%。
