该中间体在本合成路线中的序号：(V)The condensation of 3-aminno-4-phenylsulfonyl fluoride (II) with 3,4,5-trimethoxyphenol (I) in the presence of triethylamine furnished the sulfonate ester (III). The amino group of (III) was then acylated with N-Boc-beta-alanine (IV) using EDC and HOBt to yield amide (V). Finally, acid cleavage of the N-Boc protecting group of (V) provided the title aminopropionamide.
