1. Claim 1: a compound having the properties of equation (1): R 1 is selected from - C (o) nh483222；-C (O) NH (CH₃) and -CN； R² is - (X) -R⁴,Where - (x) is a link, - ch8322-u -；and R⁴ is selected from H； C₁₋₃ alkyl,a. One to four groups were selected from - f y Oh； halogen； - CN； - so832221-c83183323；-C (O) N (alquil C)If - (x) is not -- O-NHC (O) R o -N (CH) C (O) Rprovided that - (X) - is -CH₂- and where R⁵ is selected from C₃₋₆ cycloalkyl and C₁₋₃ alkyl,optionally substituted with one to three -F groups； -NHSO₂-C₁₋₃-alkyl；-CH (cyclopropyl) NHSO₂-C₁₋₃-alkyl；-OCH₂C (O) N (C₁₋₃ alkyl) ₂,If - (x) - is - ch8322a；-S (3DO) (3DNH) CHIf - (x) - is - ch8322a；heterocyclyl selected from tetrahydropyranyl, tetrahydrofuranyl, pyrrolidinyl, 1,1-dioxo [1,2] -thiazine, morpholinyl, oxazolidinyl, piperidinyl, azetidinyl, wherein said heterocyclyl is optionally substituted with one to three groups selected from -C (O) alkyl C₁₋₃,-Halogens - Oh, oxo and c832131 asphalt；-C (o) - isopropene, the condition is - (x) - sea-ch832222；a. The isomers were selected from morfolin-4-ilo, pirrolidin-1-ilo and piperidin-1-ilo, which can be replaced by one or two groups selected from - F and - Oh, cyclopentadienediol c83331 replaced by - CN u-oh；and R³ is H or C₁₋₃-alkyl optionally substituted with -OH； or R² and R³ together form a fused five-membered cycloalkyl ring optionally substituted with -OH； or one of its salts or stereoisomers.Reivindicación 1: Un compuesto, caracterizado porque tiene la fórmula (1) en donde: R¹ se selecciona de -C(O)NH₂, -C(O)NH(CH₃) y -CN； R² es -(X)-R⁴, en donde -(X)- es un enlace, -CH₂- u -O-； y R⁴ se selecciona de H； alquilo C₁₋₃, opcionalmente sustituido con uno a cuatro grupos seleccionados de -F y -OH； halógeno； -CN； -SO₂-alquilo C₁₋₃； -C(O)N(alquil C₁₋₃)₂, siempre que -(X)- no sea -O-； -NHC(O)R⁵ o -N(CH₃)C(O)R⁵, siempre que -(X)- sea -CH₂- y en donde R⁵ se selecciona de cicloalquilo C₃₋₆ y alquilo C₁₋₃, opcionalmente sustituido con uno a tres grupos -F； -NHSO₂-al
