The present invention relates to a novel method of producing a compound of Formula (I) from a compound of formula (II) by a novel cyclisation process, as well as a method of producing an acid adduct of the compound of Formula (I) wherein L represents a leaving group, and R represents hydrogen, a substituted or unsubstituted linear, branched and/or cyclic alkyl group that may contain one or more hetero atoms in the linear, branched and/or cyclic alkyl chain, a substituted or unsubstituted aromatic or heteroaromatic group, a substituted or unsubstituted linear, branched and/or cyclic aralkyl or heteroaromatic alkyl group that may contain one or more hetero atoms in the linear, branched and/or cyclic alkanediyl chain, or a substituted or unsubstituted alkylaryl or alkyl heteroaromatic group with at least one linear, branched and/or cyclic alkyl residue that may contain one or more hetero atoms in the linear, branched and/or cyclic alkyl chain.
