To a solution of cystine (1 gm, 4.2 mmol) in ammonium hydroxide (10 mL) in a screw-capped vial was added O-methylisourea hydrogen sulfate (1.8 gm, 10 mmol). The vial was sealed and heated to 60° C. for 16 h. The solution was then cooled and the ammonium hydroxide was removed by rotary evaporation. The solid was then dissolved in water (20 mL), filtered through a cotton plug. The product was then isolated by ion exchange chromatography using Bio-Rex 70 resin and eluting with hydrochloric acid (100 mM).
