To a stirred solution of 3-(tert-butyl)-5-(4-(4-chlorophenoxy)piperidine-1-carbonyl)benzoic acid (30 mg, 0.072 mmol, Step-1), EDC (21 mg, 0.11 mmol), HOBT (17 mg, 0.11 mmol), and N,N-diisopropylethylamine (0.28 mL, 1.61 mmol) in N,N-dimethylformamide (3 mL) was add 25% ammonium water (1 mL) at room temperature. After stirring at 60° C. for 2 hours, the mixture was poured into water (5 mL). This was extracted with ethyl acetate (5 mL) and washed with water (5 mL). The organic layer was dried over sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica-gel column chromatography (NH-gel, eluting with ethyl acetate) and then preparative LC-MS to give 10.4 mg (35% yield) of the title compound.
