Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 1-Methyl-1,2,3,4-tetrahydroisoquinoline hydrochloride, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 111635-08-6
2-amino-tetrahydro-isoquinolene derivatives and a process for the preparation thereof and pharmaceutical compositions containing same
Diuretic and saluretic tetrahydro-isoquinoline derivatives of the Formula (I) STR1 wherein R stands for hydrogen or chlorine, R1 and R2 are hydrogen, methoxy or ethoxy, and R3 and R4 are hydrogen or methyl, and a process for the preparation thereof as well as pharmaceutical compositions containing as active ingredients isoquinoline derivatives of the Formula (I). The compounds of Formula I are prepared by reacting a 2-amino-tetrahydro-isoquinoline derivative of the Formula (II) STR2 with a carboxylic acid derivative of the Formula (III) STR3 wherein x stands for chlorine, –OH, –OCH2 CN, –OCH3, –OC2 H5, –OCOOCH3 or –OCOOC2 H5 R5 and R6 stand for hydrogen or together from CHN(CH3)2 and in case of the Formula (Ia) STR4 splitting off the protective group in alkaline medium.
