The process may include reacting a compound of the formulawith a water-removing reagent. Also, when X is a halogen, the process may include reacting a compound of the formulawith a halogenating agent or a sulfonylating agent. Alternatively, when X is a halogen, the process may be carried out by reacting a compound of the formula IVwhere R2and R3are defined organic groups with a compound of the formula halogen-C(—O)—O—C1 -C8alkyl, halogen-C(—O)—O-aryl or halogen-C(—O)—O-benzyl.
