반응 단계
The substitution of the keto group by Cl, with formation of the aromatic pyrmidine ring, takes place under standard conditions. A mixture of 18 ml of POCl3 and 6 g of 3,4-dihydro-4-oxo-2-(pyridin-3-yl)-6-methylthieno[2,3-d]pyrimidine with addition of 1.8 ml of N,N-dimethylaniline is boiled for 4 hours. After customary work-up, 5 g of 4-chloro-2-(pyridin-3-yl)-6-methylthieno[2,3-d]pyrimidine are obtained.
