Reaction Steps

To a solution of 16.5 g of 85% KOH in 250 ml ethanol was added 25.0 g of 2-cyanothioacetamide. After all of this reagent had dissolved, 44.8 g of bromopinacolone was added dropwise over ca 5 min. The reaction temperature spontaneously climbed to 65° C. and a white solid began to deposit. The mixture was stirred and heated at reflux for 1 hour, cooled, poured into 1000 ml water, and extracted with ether. The extract was washed with brine, dried (MgSO4), and concentrated. Kugelrohr distillation of the residual oil gave 23.3 g of the desired product as a light yellow oil b.p. 90°-95° C. (1 mm Hg).
