Abstract
2-Pyridin-3-ylbenzoxazoles were synthesized by the reaction between 3-pyrid inecarboxaldehyde and substituted o-aminophenols in the presence of iodoben zene diacetate. The resulting benzoxazoles 3 were treated with methyl iodid e to give the corresponding pyridinium salts 4 which underwent the hydride reduction with sodium borohydride or sodium cyanoborohydride to produce 2-( 1-methyl-1,2,5,6-tetrahydropyridin-3-yl)benzoxazole borane complex derivati ves.
