Participants

Reaction Steps

After 4.67 g (11 mmol) of (N-methoxycarbonylmethyl-1,3-benzodioxol-5-ylamino)-N-t-butoxycarbonyl-S-methyl-L-cysteinamide were dissolved in 100 ml of ethyl acetate, an excess of hydrochloric acid was ebulated. A precipitate so formed was collected by filtration, washed with ether and then dried under reduced pressure, whereby 3.3 g of (N-methoxycarbonylmethyl-1,3-benzodioxol-5-ylamino)-S-methyl-L-cysteinamide hydrochloride were obtained (yield: 83%).
