Procedure

0.15 ml of triethylamine and 0.07 ml of methanesulfonyl chloride were added to 10 ml of a tetrahydrofuranmethylene chloride suspension containing 0.31 g of N-benzyloxycarbonyl-trans-4-[(5-hydroxylmethyl-2-isoindolinyl)carbonyl]cyclohexylamine under ice-cooling, and the mixture was stirred under ice-cooling for 1 hour. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. After the extract was dried over sodium sulfate, the solvent was removed under reduced pressure. To the residue were added 5 ml of dimethylformamide and 0.25 ml of morpholine, and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. After the extract was dried over anhydrous sodium sulfate, the solvent was removed under reduced pressure. The residue was purified by silica gel chromatography (solvent: chloroform-methanol=100:1). This compound was treated with palladium-carbon under hydrogen atmosphere to obtain trans-4-[(5-morpholinomethyl-2-isoindolinyl)carbonyl]cyclohexylamine (Reference Example 13-24 in Table 8).
