실험 절차

9.7 g (42.3 mmol) of 2-chloro-6,7-dihydrothieno[3,2-d]pyrimidin-4-yl)propylamine (VIII) and 25.7 mL (169.2 mmol) of 1-phenylpiperazine (III) are placed in 200 mL of dioxane (carried out in 10 batches), then reacted for 1 hour at 160° C. in the microwave. The reaction mixture is concentrated by evaporation, the residue is combined with 250 mL of water. Then the mixture is suction filtered, washed with water, and dried. The residue is stirred with acetonitrile, then recrystallized from isopropanol. 8.3 g of the product (I) (55%) is obtained as a powder (m.p. 121° C.). 1H NMR (400 MHz, DMSO): 7.22 (2H, t); 6.97 (2H, d); 6.79 (1H, t); 6.43 (2H, t); 3.81-3.69 (4H, m); 3.37-3.19 (4H, m); 3.19-3.09 (4H, m); 2.99 (2H, t); 1.62-1.47 (2H, m); 0.87 (3H, t).
