Reaction Conditions

Reaction Steps

The mixture of cyclopentanecarbonyl chloride (13 mg, 0.1 mmol) and ammonium isothiocyanate (7.6 mg, 0.1 mmol) in acetone (1.0 mL) was heated at 40° C. for 3 h. To the above reaction mixture, 3-(5-amino-2-methylphenyl)-1,7-dimethyl-1,6-naphthyridin-2(1H)-one (15) (27.5 mg, 0.1 mmol) was added at rt and stirred for 30 min. The solvent was removed under vacuum to yield N-(3-(1,7-dimethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-4-methylphenylcarbamothioyl)cyclopentanecarboxamide 27, which was used without purification. MS m/z 435.2 (M+1).
