Imidazolidinone derivatives of the formula ##STR1## where R, R.sub.1, R.sub.2 and R.sub.3 independently are hydrogen or lower alkyl, X represents one or two substituents selected from the group lower alkyl, halo, lower alkoxy, trifluoromethyl, and their pharmaceutically-acceptable acid salts. The compounds are prepared essentially by the method described by Wright in J. Med. Chem. 9, 852 (1966). The compounds have high depressant activity on the central nervous system.
式子为 ##STR1## 的咪唑啉酮衍生物,其中R、R.sub.1、R.sub.2和R.sub.3独立地为氢或较低的烷基,X代表从较低的烷基,卤素,较低的烷氧基,三氟甲基等组成的一个或两个取代基,以及它们的药学上可接受的酸盐。这些化合物基本上是通过Wright在J. Med. Chem. 9, 852 (1966)中描述的方法制备的。这些化合物对中枢神经系统有很高的抑制作用。
