Participants

Reaction Steps

0.300 g (0.90 mmol) of 4-chloro-2-(4-phenylpiperazin-1-yl)-6,7-dihydrothieno[3,2-d]pyrimidine (V) is placed in 4 mL of cyclohexylamine, then reacted for 0.1 hours at 130° C. in the microwave. Then the reaction mixture is concentrated by evaporation, the residue is stirred with water and suction filtered. 0.120 g of product I (34%) is obtained as a powder. 1H NMR (400 MHz, DMSO): 7.22 (2H, t); 6.97 (2H, d); 6.79 (1H, t); 6.08 (1H, d); 3.93-3.81 (1H, m); 3.80-3.69 (4H, m); 3.22 (2H, t); 3.18-3.11 (4H, m); 2.98 (2H, t); 1.92-1.79 (2H, m); 1.79-1.66 (2H, m); 1.66-1.55 (1H, m); 1.37-1.21 (4H, m); 1.18-1.04 (1H, m).
