  Process for the preparation of substituted thiazolines of the formula (I) 1 in which Ar is a phenyl, naphthyl, thienyl, pyridyl or quinolinyl radical which can optionally be substituted by one or more substituents from the group consisting of halogen, OH, benzyloxy, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, COOR 1 where R 1 is H or C 1 -C 4 -alkyl, by coupling of (S)-&agr;-methylcysteine hydrochloride of the formula (II) 2 with a nitrile of the formula (III) Ar—CN in which Ar is as defined above, or a corresponding C 1 -C 4 -alkyl imidate, in which (S)-a-methylcysteine hydrochloride of the formula (II) is reacted in a suitable solvent with a nitrile of the formula (III) or a corresponding C 1 -C 4 -alkyl imidate in the presence of a tertiary base at a pH of 6.5 to 10 at 50° C. up to the reflux temperature to give the corresponding thiazoline of the formula (I), and processes for the preparation of (S)-&agr;-methylcysteine hydrochloride and its use for the preparation of thiazolines of the formula (I).

  制备式(I)的取代噻唑环的过程，其中Ar是苯基、萘基、噻吩基、吡啶基或喹啉基，可以选择性地由卤素、OH、苄氧基、C1-C4烷基、C1-C4烷氧基、COOR1（其中R1为H或C1-C4烷基）中的一个或多个取代基取代，通过(S)-α-甲基半胱氨酸盐酸盐的配对反应，配对反应的反应物为式(II)2和式(III)Ar—CN的腈或相应的C1-C4烷基亚胺，其中(S)-α-甲基半胱氨酸盐酸盐的配对反应物式(II)在适当的溶剂中与式(III)的腈或相应的C1-C4烷基亚胺在三级碱存在下，在pH为6.5至10、50℃至回流温度下反应，得到相应的式(I)的噻唑环，以及制备(S)-α-甲基半胱氨酸盐酸盐的过程及其用于制备式(I)的噻唑环的方法。
