D-Pantetheine 4'-phosphate (VIa) and D-pantothenoyl-L-cysteine 4'-phosphate (VIb) was prepared by two different routes. The first involved reaction of D-pantothenonitrile 4'-dibenzyl phosphate (II) with cysteamine or L-cysteine followed by acid hydrolysis and then reduction with sodium in liquid ammonia. In the second route, D-pantothenonitrile 4'-phosphate (VII) was treated with cysteamine or L-cysteine to form thiazoline (VIII), which was then hydrolyzed.
