The present invention aims to provide a novel low-molecular-weight compound exhibiting an orexin receptor agonist activity and expected to be useful as a prophylactic or therapeutic agent for narcolepsy and the like. The present invention provides a compound represented by the formula (I):
wherein each symbol is as defined in the description, or a pharmaceutically acceptable acid addition salt thereof, which has an orexin receptor agonist activity, and an orexin receptor agonist containing the compound or a pharmaceutically acceptable acid addition salt thereof.
Nitroaromatic ketones are readily prepared by nucleophilic aromatic substitution of hydrogen in nitroarenes by electrochemical oxidation. Carbanions of various ketones were added to selected nitroarenes in DMF/ketone mixtures leading to formation of the sigma(H) complexes. The reaction was promoted using potassium tert-butoxide as a base. Useful yields were achieved (80-100%) in the C-arylation of ketones. In most cases, the process proceeded with high selectivity. This new method represents an environmentally favourable route for obtaining nitroaromatic ketones.

the Claisen decarboxylation reaction. An efficient synthesis of 6-substituted 3-(alkoxycarbonyl)-5-aryl-α-pyrones is reported. This methodology consists of the successive manipulation of an addition–elimination reaction between benzyl ketone derivatives and dimethyl methoxymethylenemalonate, and an acid-catalyzed condensation reaction. The synthesis is applicable to various 5-p-substituted-aryl 6-substituted
