76). Recent studies have revealed the importance of glutamate in higher cranial nerve function. Glutamic acid is released from nerve endings and regulates neuronal activity or neurotransmitter release via glutamate receptors present in the postsynaptic membrane or nerve endings. Glutamate receptors are currently roughly classified into two categories based on various pharmacological and physiological studies. One is a receptor with a built-in ion channel, and the other is a metabotropic receptor (Hollmann M. and Heinema).
nn S., Annu. Rev. Neurosci., 17 (1994) 31-108). Molecular biological studies have reported that at least eight different subtypes of mGluR1 to mGluR8 are present in the metabotropic glutamate receptor (hereinafter sometimes referred to as mGluR). mG
luR is coupled to phospholipase C via G protein, and receptors (mGluR1 and mGluR5) that promote production of inositol triphosphate (IP3) and mobilization of calcium ions into cells, and are coupled to Gi protein. Receptor that suppresses cAMP production (mGluR

141-144; ibid, 34 (1995) 1033-1041). Furthermore, it has been reported that (S) -CHPG has an effect of slowing the avoidance reaction of thermal and mechanical pain stimuli in rats (Young, MR et al., Br. J. Pharmacol., 114 (199).

That is, the above reports indicate that compounds acting on mGluR1 are useful for epilepsy, pain, inhibition of nerve cell death, and benzodiazepine withdrawal syndrome. Since WO99 / 44639 confirmed the effectiveness of the mGluR1 antagonist in a rat cerebral infarction model, it is considered to be useful as a preventive / therapeutic agent for cerebral infarction. Furthermore, it was confirmed that the mGluR1 antagonist improves the reduction in the pain threshold in the neuropathic pain model (WO

The above-mentioned production method is not limited to the substituents in the formula, but is widely applied when the compounds of the present invention have similar substituents or when the reaction substrate and the reaction reagent are opposite. The compound of the present invention thus produced is isolated or purified as a free salt or a salt thereof. Isolation
Purification is carried out by applying ordinary chemical operations such as extraction, concentration, evaporation, crystallization, filtration, recrystallization and various chromatographies. Various isomers can be separated by selecting an appropriate starting compound or by utilizing the difference in physical properties between isomers. For example, the optical isomers can be stereoisomerized by selecting an appropriate raw material or by the racemic resolution method of a racemic compound (for example, a method of leading to a diastereomeric salt with a general optically active base to perform optical resolution). It can lead to chemically pure isomers.
