2-Bromo-5-hydroxypyridine → 3-(Pyridin-3-yloxy)-4,5-dihydroisoxazole

Participants

Reaction Steps

3-(pyridin-3-yloxy)-4,5-dihydroisoxazole I-216a and I-216b were prepared in 2 steps from 1-(trifluoromethyl)-4-vinylbenzene using the cycloaddition conditions from Method 1. The resulting bromo-4,5-dihydroisoxazole was reacted with 2-bromo-5-hydroxypyridine using Method 5 to provide racemic compound I-216. These compounds can be separated using chiral HPLC methods known in the art. For example, see chiral HPLC Method disclosed herein. [M+H]+=389.1 m/z. Activity: B
