Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's will extend the buffering range, derivatives that result in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability.

The present invention relates to a preparation method for a tedizolid compound in Formula I. In Formula I, R is selected from hydrogen, formula A, formula B, benzyl or benzyl substituted by a substituent, the substituent is selected from a group consisting of halogen, nitryl, C.sub.1-C.sub.6 alkyl, and C.sub.1-C.sub.6 alkoxy, and R.sub.1 is C.sub.1-C.sub.6 alkyl or C.sub.1-C.sub.6 alkyl substituted by halogen. The method comprises: generating a compound having a structure as shown in Formula C and a compound having a structure as shown in Formula D by a coupled reaction under the catalysis of a metal catalyst, a substituent of R being defined as above, where X is a leaving group, the leaving group comprising chlorine, bromine, iodine, and sulfonyl oxy such as trifluoromethane sulfonic oxy, methylsulfonyl oxy and benzenesulfonyl oxy, or benzenesulfonyl oxy substituted by one or more substituents, the substituent being selected from a group consisting of halogen, C.sub.1-C.sub.6 alkyl, and C.sub.1-C.sub.6 alkoxy. ##STR00001##
