Reaction Steps
A mixture of thiocytosine (0.5 g.), N-(4-chlorobut-2-ynyl)phthalimide (1.03 g.), DMF (5 ml.) and 1,5-diazabicyclo[5,4,0 undec-5-ene (0.67 g.) was stirred for 2 hours. The solution was treated with water (20 ml.) and EtOAc (10 ml.) and the insoluble solid collected to give 4-amino-2-(4-phthalimidobut-2- ynylthio)pyrimidine (1.2 g.) m.p. 197°-202° (decomp.).
