Abstract:	3-Methylisoxazolo4,5-c]pyridine $1$ on reduction with BH₃:THF gave, via the isolable complex $4$ , the tetrahydroisoxazolopyridine $5$ . The presence of two chlorine atoms at the 4 and 6 positions directed borane attact to the isoxazole ring, yielding the aminoethylpyridine $8$ . Both types of reduction were obtained with 6-chloroisoxazolo4,5-c]pyridine $7$ .
