摘要：
2- Allylamino- 3- cyanopyrazine ( 3) was transformed into 1- allylpteridin- 4- one- 2- thiones ( 4) by the reaction with isothiocyanates, and the thiones 4 were thermally converted into 2- allylthiopteridin- 4- ones ( 5) by 3,3- sigmatropic rearrangement. The allylthio group of 5 was replaced by a butylamino group to give 2- butylaminopteridin- 4- ones ( 6).
