A method of inducing sedation in a patient comprises administering to a patient in which sedation is desired an amount effective for inducing sedation of a compound of the formula ##STR1## wherein R is H, or C.sub.1-5 or 7 -straight or branched chain alkyl: R.sub.1 is H, C.sub.1-5 or 7 -straight or branched chain alkyl or allyl; R.sub.2 is phenyl or phenyl substituted with F, Cl, Br, NO.sub.2, C.sub.1-5 straight or branched chain alkyl, C.sub.1-5 straight or branched chain alkoxy, 2,4-di-Cl, 2,4-di-F or 2,4-di-Br, with the proviso that when the phenyl group is monosubstituted with F, the F atom is not in the o-position; and R.sub.3 is H or C-1-5 straight or branched chain alkyl, with the proviso that when R.sub.3 is straight or branched chain alkyl, R.sub.2 is unsubstituted phenyl; or a pharmaceutically acceptable acid addition salt thereof.
一种诱导患者镇静的方法,包括向需要镇静的患者给予一定量的化合物,该化合物的公式为 ##STR1## 其中R为H,或C.sub.1-5 或7-直链或支链烷基;R.sub.1为H,C.sub.1-5 或7-直链或支链烷基或丙烯基;R.sub.2为苯基或被F、Cl、Br、NO.sub.2、C.sub.1-5 直链或支链烷基、C.sub.1-5 直链或支链烷氧基、2,4-二Cl、2,4-二F或2,4-二Br取代的苯基,但当苯基单取代为F时,F原子不在o-位置;R.sub.3为H或C-1-5 直链或支链烷基,但当R.sub.3为直链或支链烷基时,R.sub.2为未取代的苯基;或其药学上可接受的酸加盐。
