15 effect ammonolysis of 13 were unsuccessful, and alternately, the free acid 14 was converted into the primary amine 15 by a Curtius reaction. Nagata et al. 5 prepared the cyanohydrin of 6-methoxy-l-tetralone using diethylaluminum cyanide, and this reagent was utilized in an alternate sequence, illustrated in Scheme 11, which is two steps shorter than the sequence in Scheme I and provides better overall yields. The primary amine 15 was ...
