以甲醇和(R)-2-氨基-2-(4-羟基苯基)乙酸为原料合成D-对羟基苯甘氨酸甲酯盐酸盐的一般步骤:在氮气保护和-15℃条件下,将亚硫酰氯(1.5 mL,33.0 mmol)缓慢滴加到(R)-4-羟基苯基甘氨酸(5.00 g,29.91 mmol)的无水甲醇(25 mL)悬浮液中,同时搅拌。反应混合物逐渐升温至室温并持续搅拌过夜。随后,将黄色溶液回流30分钟。反应混合物经减压浓缩,得到灰白色固体状的D-对羟基苯甘氨酸甲酯盐酸盐。将该盐酸盐在乙醚(15 mL)中搅拌,过滤后用乙醚(2×15 mL)洗涤并干燥,最终得到白色固体状的D-对羟基苯甘氨酸甲酯盐酸盐(6.50 g,100%),其熔点为189-191℃;比旋光度[α]20D = -120.9(c 1, 1M HCl),文献值[α]25D = -121.1(c 1, 1M HCl);红外光谱(KBr)νmax/cm-1:3339(宽峰),1740(C=O),1595;核磁共振氢谱(300 MHz, DMSO-d6)δH:3.68(3H,单峰,OCH3),5.11(1H,单峰,C(2)H),6.80(2H,双峰,J=8.5 Hz,芳香族H),7.25(2H,双峰,J=8.5 Hz,芳香族H),8.70(3H,宽峰,NH3),9.86(1H,单峰,OH)。
