Participants

Reaction Steps

0.3 g of DL-(2,2,5,5-tetramethyl-4-thiazolidinyl)phenylphosphinic acid hydrochloride (prepared as described in Example 7) was suspended in boiling water and concentrated hydrochloric acid was added until a solution had formed. The solution was filtered and the filtrate was evaporated to dryness under reduced pressure. The solid residue was recrystallized from 3N hydrochloric acid to give DL-(1-amino-2-mercapto-2-methylpropyl)phenylphosphinic acid hydrochloride of melting point 190°-192° C. (decomposition).
