Abstract: The present invention relates to compounds of formula wherein X is —S— or —NH—; R3/R4 together with the N-atom to which they are attached form a non aromatic 5, 6 or 7 membered ring, which optionally contains in addition to the N-atom one additional heteroatom selected from the group consisting of O, S and N, and wherein the ring is optionally substituted by hydroxy, lower alkyl, lower alkoxy, —NR2, —CONR2, —CO-lower alkyl or benzyl; or R3/R4 form together with the N-atom to which they are attached a heterocyclic ring system, containing two or three rings and which optionally contains one or two additional heteroatoms selected from the group consisting of N and O and which has no more than 20 carbon atoms; and R, R1, R2, and R5 are as defined herein and to pharmaceutically suitable acid addition salts thereof.
