Electric Literature of 1005-38-5 , The common heterocyclic compound, 1005-38-5, name is 4-Amino-6-chloro-2-(methylthio)pyrimidine, molecular formula is C5H6ClN3S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Acetic anhydride (10.4 MI, 0. 11 MOL) was added to 6-chloro-2- (methylthio) pyrimidin-4-amine (2.5 g, 0.01 mol) and the reaction mixture was refluxed at 135 C for 5 hr. The reaction mixture was cooled to room temperature and basified to pH 7 with saturated sodium bicarbonate solution (20 ML). The mixture was partitioned between EtOAc and water, the organic layer was washed with water and brine, dried over MgS04 and concentrated to give the title compound (2.62 g). MS (ES . : 218 (MH+) for C7HGCINO3S
The synthetic route of 1005-38-5 has been constantly updated, and we look forward to future research findings.
