Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: By the use of 2-chloromethyl-4-benzylmorpholine and N-methylpiperazine, the reactin is similarly carried out as Reference example 2 to give 2-(4-methyl-1-piperazinylmethyl) morpholine.trihydrochloride as white crystals, melting at 210°-212° C.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Lithium aluminum hydride (150 mg, 4.10 mmol) was suspended in tetrahydrofuran (5 mL), and the suspension was mixed with a solution of tert-butyl 4-morpholin-2-ylmethylpiperazinecarboxylate (390 mg, 1.37 mmol) prepared as an intermediate according to Process Step 2 of Reference Example 19 in tetrahydrofuran (5 mL) added dropwise under ice-cooling, followed by heating at 60° C. under reflux for two hours. An aqueous sodium hydroxide solution (2 mol/L, 10 mL) and chloroform (50 mL) were added under ice-cooling, followed by separation. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure, to thereby yield the title compound (180 mg, in a yield of 66%). prepared as an intermediate added dropwise under ice- cooling under reflux for two hours cooling followed by separation The organic layer was dried over anhydrous magnesium sulfate the solvent was distilled off under reduced pressure
