Hydrochloric Acid → (S)-1-allyl-3-amino-3,4-dihydrocarbostyril hydrochloride

Participants

Reaction Steps

(S)-1-allyl-3-t-butyloxycarbonylamino-3,4-dihydrocarbostyril (9.7 mg) was dissolved in 4 M hydrogen chloride in 1,4-dioxane solution (2 mL) at room temperature, and a white precipitate soon formed. After 30 min the solvent was evaporated under vacuum, and the residue was twice taken up in toluene (5 mL) and evaporated to provide (S)-1-allyl-3-amino-3,4-dihydrocarbostyril hydrochloride (7.6 mg).
