실험 절차

In an example of this reaction 1,4-dihydro-alpha-naphthoic acid is reacted with thionyl chloride at room temperature for 1-6 hours to obtain 1,4-dihydro-alpha-naphthoic chloride. This compound is then reacted with an amine of the formula (3) and triethylamine in ether solvent under reflux for 0.1-3 hours to obtain a compound of the formula (1a). Compounds of the formulae (1b) and (1c) may also be produced in the same manner as just described using 3,4-dihydro-alpha-naphthoic acid and 1,2,3,4-tetrahydro-alpha-naphthoic acid, respectively as starting materials.
