3-Chloroaniline → (3-Chlorophenyl)-[2-(4-phenylpiperazin-1-yl)-6,7-dihydrothieno[3,2-d]pyrimidin-4-yl]amine

Participants

Reaction Steps

0.320 g (0.96 mmol) of 4-chloro-2-(4-phenylpiperazin-1-yl)-6,7-dihydrothieno[3,2-d]pyrimidine (V), 1.0 mL (9.5 mmol) of 3-chlorophenylamine, and 0.33 mL (1.92 mmol) of diisopropylethylamine are combined and the mixture is reacted for 0.5 hours at 130° C. in the microwave. Then the reaction mixture is combined with ethyl acetate and acidically extracted. The organic phase is dried and evaporated to dryness. The residue is combined with acetonitrile, water, and trifluoroacetic acid. The phase containing the product I is purified by chromatography through an RP column by HPLC (column: Microsorb, RP-C18, 300 Å, 10 μm, 21.4*250 mm, eluant: acetonitrile+0.1% formic acid (A), water+0.13% formic acid (B)).
