    • The present invention relates to a process for preparing optically active and racemic nitrogen-substituted 2-aminotetralins of the following Formula (I): wherein R1, R2, R3, R4, and n are set in the specification, wherein the process comprises alkylating the corresponding unsubstituted 2-aminotetralin of Formula (II): with a reactant of the Formula (III): Z—(CH2)n—R3  (III) wherein Z is a leaving group, in the presence of a base, wherein the base is selected from the group consisting of alkali metal carbonate and alkali metal bicarbonate, and wherein the amount of the base is less than about a 1.9-fold molar excess with respect to the amount of the 2-aminotetralin.
    • 本发明涉及制备下式(I)的光学活性和外消旋的氮取代的2-氨基四氢萘酚的方法:其中R1,R2,R3,R4和n被定义在说明书中,其中该方法包括将 相应的式(II)的未取代的2-氨基四氢化萘:与式(III)的反应物:其中Z是离去基团,在碱的存在下,其中碱选自碱金属碳酸盐和碱 金属碳酸氢盐,并且其中所述碱的量相对于2-氨基四氢萘的量小于约1.9倍摩尔过量。
