Participants

Reaction Steps

2-[(2S)-2-[[(2R)-2-Hydroxy-2-(4-hydroxy-phenyl)ethyl]-amino]-1,2,3,4-tetrahydronaphthalen-7-yloxy]-N,N-dimethylacetamide (210 mg) was suspended in ethanol (10.5 ml), and 1N hydrochloric acid (546 μl) was added to the suspension and the mixture was dissolved by heating. After cooling, collection by filtration of the precipitated crystals gave 2-[(2S)-2-[[(2R)-2-hydroxy-2-(4-hydroxyphenyl)ethyl]amino]-1,2,3,4-tetrahydronaphthalen-7-yloxy]-N,N-dimethylacetamide hydrochloride (100 mg) having a melting point of 165-168° C.
