Indicates an aromatic heterocyclic group with or without a protected amino group or a protected hydroxyl group. ] represents,
R 15 represents a lower alkyl group. In method A, a compound having general formula (2) is reacted with an alkylating agent having general formula (3) to produce a penem-3-carboxylic acid derivative having general formula (4), and then the penem-3-carboxylic acid derivative having general formula (4) is produced as desired. The resulting compound is subjected to a reaction to remove the carboxyl group protecting group R 11 and the corresponding protecting groups contained in R 10 and R 13 a to form a hydroxyl group,
This is a reaction for producing the target compound of the present invention having general formula (1) by subjecting it to a reaction for restoring a mercapto group and an amino group or a lower alkylamino group. In carrying out method A of the present invention, the general formula
The reaction of producing the compound having the general formula (4) by reacting the compound having the formula (2) with the alkylating agent having the general formula (3) is preferably carried out in the presence of chlorine in an inert solvent.
