2516-33-8 ,Some common heterocyclic compound, 2516-33-8, molecular formula is C4H8O, 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.
0.49 g (6.82 mmoi) cyclopropane methanol in 10 mL THF are charged with 0.42 g (11.4 mmoi) NaH and the reaction mixture is stirred at r.t. for 20 min. Then 1.00 g (5.68 mmoi) 5-bromo-2-fluoropyridine are added and the mixture is stirred at r.t. over night. The reaction is quenched by the addition of water and extracted with EtOAc. The organic layers are combined, dried over MgS04l filtered and the solvent is removed in vacuo. The crude product is purified by HPLC (MeOH/H20/FA). CgH-ioBrNO (M= 228.1 g/mol) ESI-MS: 228/229 [M+H]+ Rt (HPLC):1.14 min (method C)
