Methyl iodide → HCID 19100928, compound

Participants

Reaction Steps

To a stirred mixture of 67.7 parts of 2-amino-5-(2-hydroxyethyl)-6-methyl-4(3H)-pyrimidinone and 800 parts of ethanol were added 80 parts of a sodium methoxide solution 30%. The reaction mixture was heated to reflux temperature and 62.5 parts of iodomethane were added dropwise. Upon complete addition, stirring was continued for 4 hours at reflux temperature. The reaction mixture was evaporated and the residue was suspended in 400 parts of water. The precipitated product was filtered off, washed with 40 parts of ethanol and dried, yielding 58.3 parts (79.6%) of 2-amino-5-(2-hydroxy-ethyl)-3,6-dimethyl-4(3H)-pyrimidinone (interm. 12).
