概述
N'-[(2,3-二氢-2,2,4,6,7-五甲基苯并呋喃-5-基)磺酰基]-N-芴甲氧羰基-D-精氨酸为氨基酸衍生物，可用作医药中间体。制备
a6.在反应釜中加入H-Arg(Pbf)-OH，水120L、THF，用Na2CO3调节PH＝8.5。
b6.逐渐加入Fmoc-Osu(芴甲氧羰酰琥珀酰亚胺)，控制温度15-20℃，PH＝8-9以把Arg(Pbf) 反应完，尽量避免Fmoc-Osu过量。
TLC点板跟踪反应情况，从加完Fmoc-Osu开始计算，反应时间6小时。
c6.纯化：用石油醚/乙酸乙酯(2:1)萃取；水相用HCl酸化至pH＝3，搅拌2小时。酸化温度0-10℃；加乙酸乙酯萃取产品；用饱和食盐水洗至pH达到6；无水硫酸钠干燥，真空抽滤除去固体，滤液浓缩，减压浓缩得到固体，真空干燥得到产品。
产品纯度99.6％，最大单杂0.09％，L型异构体0.15％。
