Acetamidine → N-((4-Amino-2-methyl-5-pyrimidinyl)methyl)formamide

Participants

Reaction Steps

The α-methoxymethylene-β-formylaminopropionitrile solution and the acetamidine solution are combined. The mixture is reacted at 25°C for 10 minutes. The reaction mixture is subjected to concentration at not higher than 40°C to give crystals. The produced crystals are washed with 50 parts by volume of ethanol, whereby 24.8 parts of 2-methyl-4-amino-5-formylaminomethylpyrimidine is obtained as crystals (Purity: 93 %). The ethanol washing is concentrated to give 16 parts of 2-methyl-4-amino-5-formylaminomethylpyrimidine as crystals (Purity: 47.5 %).
