发明名称 METHOD OF PREPARATION OF (S)-N-TERT-BUTYL-1,2,3,4-TETRAHYDROISOQUINOLINE-3-CARBOXAMIDE
摘要 A new method is described here for the synthesis of (S)-N-tert-butyl-1,2,3,4-tetrahydroiso-quinoline-3-carboxamide comprising the following steps: a) (3S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid is reacted with formic acid to give the compound of formula: (I) b) the compound thus obtained is reacted with tert-butylamine to give the compound of formula: (I) c) the compound thus obtained is then treated with acids to give the desired compound.The method in question makes it possible to obtain (S)-N-tert-butyl-1,2,3,4-tetrahydroiso-quinoline-3-carboxamide with high yields and purity without using toxic and hazardous reagents.
