Reaction Steps

3-Amino-3-(2,3-dihydro-1,4-benzodioxin-6-yl)propionic acid [synthesis according to instructions known from the literature (e.g., L. Lázár, T. Martinek, G. Bernáth, F. Fülöp, Synth. Comm. 1998, 28, 219-224)]is introduced into a vessel in methanol (about 0.5 to 1.0 mol/l) and admixed dropwise at 0° C. with 1.2 eq of thionyl chloride. When the addition has been made the reaction mixture is stirred at room temperature overnight and subsequently concentrated. The residue is dissolved in a little methanol and the product is precipitated with diethyl ether. The solid is filtered off with suction, washed repeatedly with diethyl ether and dried under reduced pressure.
