preparation example Construction
[0124] This preparation method is a step of converting the carboxyl group of the compound (I-a) prepared by the first preparation method as the compound of the present invention into a formamide group or a bioisostere of the carboxyl group.
[0125] For example, in Z 1 for-CO-NH-SO 2 -C 1-6 Alkyl or -CO-NH-SO 2 -N(C 1-6 alkyl) 2 In the case of , it can be prepared by a fusion reaction with the corresponding sulfonamide; for example, in Z 1 for-CONH 2 In the case of , it can be prepared by a fusion reaction using ammonium chloride, ammonium hydroxide, ammonia solution, etc.; for example, in Z 1 In the case of a tetrazolyl group, after being induced into formamide, it is dehydrated to induce a nitro group by a conventional method, and then reacted with sodium azide to produce it. Alternatively, the carboxyl group can be converted to its bioisostere using methods known to those skilled in the art.

preparation example 1
[0194] Under ice-cooling, ethyl trans-4-hydroxycyclohexanecarboxylate (8g), benzyl 4-hydroxybenzoate (11.69g), 1,1'-(azobiscarbonyl)dipiperidine ( 15.24 g), THF (150 ml) was added dropwise to a mixture of tributylphosphine (14.9 ml), stirred at room temperature for 2 hours, and then stirred at 60° C. for 10 hours. After returning the reaction mixture to room temperature, it was filtered, washed with THF, and the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=85:15) to give benzyl 4-{[cis-4-(ethoxycarbonyl)cyclohexyl]oxy}benzoate 8.55 g of colorless oily substance of base ester.
