Related Products of 89284-85-5 , The common heterocyclic compound, 89284-85-5, name is Methyl 2,5,6-trichloropyrimidine-4-carboxylate, molecular formula is C6H3Cl3N2O2, 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.
A mixture of I (1.5 g, 6.2 mmol) and (rac) 3-hydroxymethylmorpholine (875 mg, 7.4 mmol) with DIPEA ( 1.6 ml_, 9.3 mmol) in EtOH (30 mL) was heated at 75C for 1 h 30 min. The mixture was cooled down to rt and solvents were removed in vacuo. The oily residue was redisolved in DCM (20 mL), washed with sat. solution of NaHC03 (3 x 20 mL), brine (30 mL), dried over Na2S04 and concentrated in vacuo. Required product, intermediate II (1.860 g, 93%) was used further without additional purifications.
The synthetic route of 89284-85-5 has been constantly updated, and we look forward to future research findings.
