24686-78-0, Example 95 Synthesis of 4-[(1-benzoylpiperidin-4-yl)amino]-2-methoxybenzamide To a solution of the 4-amino-2-methoxybenzamide obtained in Example 74 (b) or Example 86 (a) (150 mg, 0.902 mmol) in methanol (7.5 ml) were added 1-benzoyl-4-piperidone (183 mg, 0.902 mmol) and acetic acid (0.052 ml, 0.90 mmol), and the resulting mixture was stirred at room temperature for 30 minutes. Then, acetic acid (0.103 ml, 1.80 mmol) and sodium cyanoborohydride (130 mg, 2.06 mmol) were added thereto, followed by stirring at room temperature for 31 hours. During this stirring, 1-benzoyl-4-piperidone (183 mg, 0.902 mmol), sodium cyanoborohydride (208 mg, 3.30 mmol) and acetic acid (0.154 ml, 2.70 mmol) were further added thereto. The reaction mixture was poured into a 1N-aqueous sodium hydroxide solution and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by a silica gel column chromatography (eluent: ethyl acetate/methanol = 100/1 to 50/1) to obtain 4-[(1-benzoylpiperidin-4-yl)amino]-2-methoxybenzamide (97 mg, 30percent). IR (neat): 3455, 3309, 2939, 1604, 1573, 14 23, 1338, 1211cm-1.
