Eleven kinds of 2-methyl-4-amino-5-[N-(3′-acylthio-5′-acyloxy-Δ2′-pentenyl-2′)]-formaminopyrimidine (O, S-diacyl-B1) were prepared by the application of acid anhydride or chlorde to the sodium salt of the thiol-type vitamin B1 homologs (B1, homo-B1, O-benzoyl-B1). These synthetic compounds were found to possess approximately the same effect as vitamin B1 in preventing B1-deficiency in Urolonca domestica.
