在-10℃條件下，將5g L-天門冬氨酸（37.6mmol）緩慢加入至含有3.8mL（41.2mmol）SOCl?的26mL無水甲醇溶液中。反應(yīng)混合物于室溫下持續(xù)攪拌2小時(shí)，隨后加入75mL二乙醚以促進(jìn)產(chǎn)物沉淀。通過過濾收集生成的白色固體，并用2×50mL乙醚洗滌，最終得到（S）-天冬氨酸-β-甲酯鹽酸鹽，產(chǎn)率為85%。產(chǎn)物為白色固體。1H NMR（300MHz，DMSO）表征數(shù)據(jù)如下：δ（ppm）= 3.05（dd，J = 3.4,4.7Hz，2H，CH?），3.78（s，3H，OCH?），4.31-4.35（m，1H，CHN）。
