Solid-phase synthesis of N-9-substituted 2,8-diaminopurines

A general and efficient solid-phase synthesis of N-9-substituted 2,8-diaminopurines from 5-nitrouracil is described. The key synthetic transformation employs a carbodiimide-mediated cyclization of a thiourea. Thiourea formation on solid phase is performed

Method for preparing 2, 4 - dichloro -5 - nitropyrimidine

The invention discloses a method for preparing 2, 4 - dichloro -5 - nitropyrimidine, wherein, 5 - nitro uracil is put into a reactor, and the reaction is stopped when the product content 50 °C 95% or more is increased to 100 °C dropwise DMF. The dichloroethane layer was removed by filtration, and the 2 mixture 4 -dichloro -5 -nitropyrimidine was distilled off under reduced pressure. The reaction conditions are easy to control, operation is simple, yield is high, production cost is low, safety and environmental protection are achieved, and industrial production can be realized.
