Merck, 251569-100G, 1,3-Dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone

Application
1,3-Dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (DMPU) can be used:
As a versatile solvent in N-alkylation of amines
O-alkylation of aldoses , and in the synthesis of poly(aryl ethers).
As urea solvent in the synthesis of 1-aryl-3,4,5-substituted pyrazoles by cyclocondensation of arylhydrazine hydrochlorides with 1,3-diketones.
As an additive in asymmetric cyanoamidation.

DMPU/HF can be used as a nucleophilic fluorinating agent in fluoro-Prins reaction for the synthesis of substituted 4-fluorotetrahydropyrans and 4-fluoropiperidines.
Versatile solvent employed in N-alkylation of chiral, primary amines, O-alkylation of aldoses, and in the synthesis of poly(aryl ethers).
