The invention provides antifungal agents of the formula: ##STR1## and their pharmaceutically acceptable salts, wherein R is phenyl optionally substituted by 1 to 3 substituents each independently selected from halo and CF.sub.3 ; R.sup.1 is C.sub.1 -C.sub.4 alkyl; R.sup.2 is H or C.sub.1 -C.sub.4 alkyl; and "Het", which is attached to the adjacent carbon atom by a ring carbon atom, is selected from pyridinyl, pyridazinyl, pyrimidinyl, pyrazinyl and triazinyl, "Het" being optionally substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halo, CF.sub.3, CN, NO.sub.2, NH.sub.2, --NH(C.sub.1 -C.sub.4 alkanoyl) or --NHCO.sub.2 (C.sub.1 -C.sub.4 alkyl).
该发明提供了化学式为:##STR1##的抗真菌剂及其药用盐,其中R为苯基,可选择1至3个取代基,每个取代基独立选择自卤素和CF.sub.3;R.sup.1为C.sub.1 -C.sub.4烷基;R.sup.2为H或C.sub.1 -C.sub.4烷基;而与相邻碳原子连接的“Het”可选择自吡啶基、吡啶嗪基、嘧啶基、吡嗪基和三嗪基,“Het”可选择性地被C.sub.1 -C.sub.4烷基、C.sub.1 -C.sub.4烷氧基、卤素、CF.sub.3、CN、NO.sub.2、NH.sub.2、--NH(C.sub.1 -C.sub.4醇酰基)或--NHCO.sub.2(C.sub.1 -C.sub.4烷基)取代。
