실험 절차

To a solution of 500 mg (1.16 mmol) of the above 5-chloro-7-[2-(3-chloro-pyridin-2-yl)-5-methoxy-2H-pyrazol-3-yl]-1H-8-oxa-1,2,6-triaza-cyclopenta[a]naphthalen-9-one in 10 mL of N,N-dimethylformamide is added 396 mg (3.49 mmol) of 3-methyl-thietan-3-ylamine. The reaction is stirred at 60° C. for 72 hours and then concentrated in vacuo. The residue is taken-up with water and ethyl acetate. The phases are separated and the aqueous layer is washed three times with ethyl acetate. The combined organic layers are washed with brine, dried over MgSO4 and concentrated in vacuo. Purification of the residue by flash chromatography (SiO2, hexanes/ethyl acetate 1:2) affords 276 mg (44%) of the product as a white solid; LC/MS:532/534 (M+H)+, m.p.: 162-165° C.
