Title:	Method for preparing N.sup.2 -arylsulfonyl-L-argininamides
Abstract:	A method for preparing N.sup.2 -(3-(a hydrogen atom or a lower alkyl)-8-quinolinesulfonyl)-N.sup.G -nitro-L-arginine which comprises the step of condensing N.sup.G -nitro-L-arginine and 3-(a hydrogen atom or a lower alkyl)-8-quinolinesulfonyl chloride. The method achieves an extremely efficient and high yield preparation of N.sup.2 -arylsulfonyl-L-arginineamides that are useful as active ingredients of medicaments. Also provided is a novel N.sup.2 -(3-(a hydrogen atom or a lower alkyl)-8-quinolinesulfonyl)-N.sup.G -nitro-L-arginine compound which can be used as synthetic intermediate for the manufacture of (2R,4R)-4-methyl-1-[N.sup.2 -(3-methyl-1,2,3,4-tetrahydro-8-quinolinesulfonyl)-L-arginyl]-2-piperidine -carboxylic acid.
