[0500] Preparations of the above-mentioned dosage forms can be carried out according to known production methods commonly used in the field of pharmaceuticals. At this time, if necessary, it can be produced containing excipients, binders, lubricants, disintegrants, sweeteners, surfactants, suspending agents, emulsifying agents, etc., which are conventionally used in the field of pharmaceutical preparations.
[0501] Tablets can be prepared, for example, by containing excipients, binders, disintegrants or lubricants. The preparation of pellets and granules can be carried out, for example, with excipients, binders or disintegrants. In addition, powders and capsules can be prepared, for example, with excipients. The preparation of a syrup can contain a sweetener, for example. The preparation of an emulsion or a suspension can be carried out by containing, for example, a surfactant, a suspending agent, or an emulsifying agent.
[0502] Examples of excipients include lactose, gl...
Embodiment
[0514] Hereinafter, although an Example, a comparative example, and a reference example demonstrate this invention in detail, this invention is not limited to these.
[0515] In the following description, the solvent names shown in the NMR data indicate the solvents used for the measurement. In addition, the 400 MHz NMR spectrum was measured using the JNM-AL400 nuclear magnetic resonance apparatus (made by JEOL Ltd.). The chemical shift is based on tetramethylsilane, expressed in δ (unit: ppm), and the signals are represented by s (single line), d (double line), t (triple line), q (quadruple line), quint ( Quintuplet), sept (sevenfold), m (multiplet), br (broad peak), dd (double doublet), dt (double triplet), ddd (double doublet doublet) , dq (double quartet), td (triple double line), tt (triple triple line) represent. The ESI-MS spectrum was measured using Agilent Technologies 1200 Series, G6130A (manufactured by Agilent Technology). All solvents used commercially availabl...

[0524] (Reference example 1) the synthesis of thick 4-ethylmethylaminopiperidine:
[0525] [chemical formula 22]
[0526]
[0527] To a solution of benzyl 4-oxopiperidine-1-carboxylate (0.500 g, 2.14 mmol) in dichloromethane (12.0 mL) was added ethylmethylamine (0.230 mL, 2.68 mmol), Acetic acid (0.0120 mL, 0.214 mmol) and sodium triacetoxyborohydride (0.681 g, 3.22 mmol), and the reaction solution was stirred at room temperature for 16 hours. The reaction solution was cooled to 0 °C. Saturated aqueous sodium bicarbonate solution was added to the reaction liquid, followed by extraction with chloroform. The organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by flash column chromatography (NH silica gel, chloroform / methanol). The obtained crude product was dissolved in methanol (8.0 mL), palladium / carbon (10% wet, 0.185 g, 0.174 mmol) was added at room temperature, and stirred...
