PROBLEM TO BE SOLVED: To provide a method for preparing 4-amino-5-chloro-2-ethoxy-N-[[4-(4-fluorobenzyl)-2-morpholinyl]methyl]benzamide in high yield with high purity. SOLUTION: The method includes steps of dissolving a crude matter containing 4-amino-5-chloro-2-ethoxy-N-[[4-(4-fluorobenzyl)-2-morpholinyl]methyl]benzamide in a solvent containing an amide solvent and subsequently crystallizing 4-amino-5-chloro-2-ethoxy-N-[[4-(4-fluorobenzyl)-2-morpholinyl]methyl]benzamide from the resulting solution.
