Reaction Steps

This compound known in the literature was made by an alternative route in analogy to Heterocycles 1994, 39 (1), 139: Tosylmethylisocyanide (TOSMIC) (3.57 g) was suspended in ethanol (50 ml) and 2-picolinealdehyde (2.0 g) was added. Sodium cyanide (92 mg) was added in one portion at 15° C. and the mixture was allowed to stir—the internal temperature rose to 26° C. and a clear solution was obtained. The mixture was cooled again to 15° C. and the intermediate oxazoline derivative precipitated. The suspension was filtered and the solid intermediate was washed with ether/hexanes 1:1 and dried in vacuo (yield: 4.77 g).
