Participants

Reaction Steps

A solution of 2N sodium hydroxide (11.3 mL, 22.7 mmol) was added to D-(−)-penicillamine (2.5 g, 16.8 mmol) at 0° C. Once all the solid was dissolved, a solution of 3-bromopropanol (3.03 g, 21.8 mmol) in ethanol (17 mL) was slowly added at 0° C. and the resulting mixture was stirred for 15 h at room temperature. The mixture was treated with 1N hydrochloric acid until pH is ˜6 and the solvents were removed to obtain (2S)-2-amino-3-[(3-hydroxypropyl)sulfanyl]-3-methylbutanoic acid as a white solid. This solid was used for the next step without further purification; Electrospray Mass Spec 208.1 (M+H)+
