실험 절차

1-Chloroethyl chloroformate (572 mg, 4 mmol) was added dropwise to the solution of 7-benzyl-N-(4-(trifluoromethyl)phenyl)-5,6,7,8-tetrahydro-2-(methylthio)pyrido[3,4-d]pyrimidin-4-amine (860 mg, 2 mmol) and diisopropylethyl amine (516 mg, 4 mmol) in 1,2-dichloroethane (5 mL, anhydrous) at 0° C. After addition, the reaction mixture was stirred at room temperature for 1 hr. Solvent was removed in vacuo, residue was dissolved in methanol (10 mL) and was stirred at room temperature overnight. Solvent was removed in vacuo, residue was dissolved in ethyl acetate and was washed by sodium bicarbonate's aqueous solution, brine and dried over sodium sulfate. Solvent was removed in vacuo and residue was triturated by diethyl ether to yield the product as a beige solid (454 mg, 67%).
