FIELD: chemistry. n SUBSTANCE: invention relates to a compound of formula (I) wherein A is selected from substituted 3–12 membered cyclohydrocarbyl or heterocyclic hydrocarbyl or cyclic heterohydrocarbyl, wherein said heterocyclic hydrocarbyl or cyclic heterohydrocarbyl contains 1 or 2 heteroatoms in the ring, independently selected from N and S; B is selected from C(=O); X is a single bond; D and L are independently selected from CH 2 ; T is C; M is selected from C(Y)(R 1a ), when Q is selected from C (R 1b )(R 1c ), or M is selected from C(R 1b )(R 1c ) when Q is selected from C(Y)(R 1a ); where A is selected from the structural unit shown in formula (A 1 ) or (A 2 ), the values of the remaining radicals are indicated in the claims. (I) (A 1 ) (A 2 ). n EFFECT: technical result: obtaining new compounds of formula (I), having the properties of orexin receptor antagonists. n 8 cl, 1 tbl, 37 ex |
