Reaction Steps

A microwave reaction vial is charged with racemic ompound I-10 (1.0 equiv) and the sodium salt of 1,2,4-triazole (2.0 equiv). The reagents are dissolved in N-methylpyrrolidine (0.18 M with respect to compound I-10). The mixture was sealed and heated in a microwave reactor at 100° C. for 30 min. Excess water is added and a brown solid crashes out which is isolated using vacuum filtration and dried to provide the desired 3-(1H-1,2,4-triazol-1-yl)-4,5-dihydroisoxazole I-34a and I-34b. These compounds can be separated using chiral HPLC methods known in the art. For example, see chiral HPLC Method disclosed herein. [M−H]−=306.1 m/z. Activity: C.
