Procedure

13.5 g of S-(β-aminoethyl)mercaptoacetic acid and 10.8 g of 2,2-dimethoxy propane are added, successively, to a solution of 7.3 g of gaseous hydrochloric acid in 20 cc of methanol. The solution is permitted to stand for 12 hours at ambient temperature. The flakes formed (17.5 g) are filtered and washed with ethyl acetate. Fusion point = 100° C.
