A series of novel 4-(4-amino phenyl) morpholine-3-one substituted coumarin derivatives have been prepared by chloramine coupling reaction and were identified. The novel synthetic route involves nucleophilic substitution reaction of 4-chloro-3-nitro-2H-chromene-2- one with 4-(4-amino phenyl)morpholine-3-one. Due to the presence of nitro group in coumarin derivatives make substitution reaction easy and convenient at low temperature. Using DMF as solvent and K2CO3 as base various substituted 4-(4-((3-nitro-2-oxo-2H-chromen- 4-yl)amino)phenyl)morpholine-3-one derivatives (YS-1 to YS-10) can be obtain in good yield and high purity. Structural characterization of all synthesized compound was done by NMR, Mass and IR spectra.

This invention provides compounds that are antagonists of melanin concentrating hormone receptor-1 (MCH-R1). The compounds are represented by formula (I): where m is zero or one, n is zero to two, Y is oxygen or -N (R9)-, R1, R2, R3, R4, R5, R9, and Ring A are defined in the specification. Coumarin and quinolone compounds where R1 and R2 together form a fused benzo ring are preferred. The invention also provides compounds of formula (VI) where the coumarin moiety is replaced by a quinazolinone ring. The compounds are useful for treating MCH-R1-related disorders, particularly overweight conditions including obesity.
