Embodiment 1
[0280] 【Chemical 21】
[0281]
[0282] (2R)-2-{Cyclopropyl[4-methoxy-3-(3-methoxypropoxy)benzyl]carbamoyl}ylmorpholine-4-carboxylic acid tert-butyl ester (reference example Compound 8 (368 mg) was dissolved in chloroform (4 ml), cooled in an ice bath, 4N hydrogen chloride / dioxane (1 ml) was added, and stirred at room temperature for 2 hours. Cool in an ice bath, add water, and separate the organic phase. Add saturated aqueous sodium bicarbonate solution to the aqueous phase to adjust the pH value to 9, then extract with chloroform. The organic phase was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by NH-silica gel column (column solvent: n-hexane / ethyl acetate=1 / 1→ethyl acetate) to obtain colorless oil (2R)-N-cyclopropyl-N-[4-methyl Oxy-3-(3-methoxypropoxy)benzyl]morpholine-2-carboxamide (230 mg). The obtained compound was dissolved in chloroform (1 ml), cooled with ice water, 4N hydr...
Embodiment 2
[0285] 【Chemical 22】
[0286]
[0287] (2R)-2-{[4-Benzyloxy-3-(3-methoxypropoxy)benzyl]cyclopropylcarbamoyl}morpholine-4-carboxylic acid tert-butyl ester (reference The compound of Example 9 (217 mg) was dissolved in chloroform (1 ml), cooled in an ice bath, 4N hydrogen chloride / dioxane (1 ml) was added, and then stirred at room temperature for 2 hours. After concentration under reduced pressure, water (1ml) and diethyl ether (2ml) were added to the residue and stirred gently, and the diethyl ether was removed by decantation. Then obtain colorless powder (2R)-N-[4-(benzyloxy)-3-(3-methoxypropoxy)benzyl]-N-cyclopropylmorpholine-2 by lyophilization - Formamide hydrochloride (166 mg).

[0290] 【Chemical 23】
[0291]
[0292] (2R)-2-([3-Benzyloxy-5-(3-methoxypropoxy)benzyl]cyclopropylcarbamate)morpholine-4-carboxylic acid tert-butyl ester (reference example 10 Compound 150 mg) was obtained in the same manner as Example 2 to obtain colorless viscous oil (2R)-N-[3-(benzyl)-5-(3-methoxypropoxy)phenoxy]-N-cyclopropane Methyl-morpholine-2-carboxamide hydrochloride (107 mg).
