Abstract
A process for producing heterocyclic compounds, of the general formula ** (See formula) ** where Z represents one of the groups ** (See formula) ** R1 is hydrogen, halogen or lower alkyl; R2, R3 and R4 each represent hydrogen or lower alkyl; A is a carbonyl group or a methylene group; B is a thio, sulfinyl or sulfonyl group; R5 is hydrogen, lower alkyl or carboxy lower alkyl; and R6 is hydrogen, lower alkyl or lower alkanoyloxy, and its acid addition salts, which process is characterized in that it consists in reacting a compound of the general formula ** (See formula) ** where R1, R3 and R4 have the above meaning and Hal represents halogen, with a mercaptoic acid of the general formula HS- Z'-COOH (III) where Z 'represents one of the groups ** (See formula) ** R5 has the meaning indicated above; Y R6 is hydrogen or lower alkyl, to form a compound of the formula ** (See formula) ** where R1, R3, R4 and Z ', have the above meaning, in oxidizing, if desired, the thio group of the last compound to convert it into a sulfonyl group, in reducing, and cyclizing the resulting compound, in converting, if desired, the carbonyl group of the resulting product into a methylene group, in oxidizing, if it is desired, a thio group to form a sulphinyl or sulphonyl group, in N-alkylated, if desired, an N-unsubstituted product, in introducing, if desired, an alkanoyloxy group as a substituent R6 and, if desired, in converting a resulting base in an acid addition salt.
