Reaction Conditions:

with sulfuric acid in 1,2-dichloro-benzene at 50; for 15 h;Solvent;Temperature;

Steps:

1-7 Example 2

1-(3-hydroxymethylpyridine)-2-phenyl-4-methyl-piperazine 10g (1 equivalent) was placed in 30ml of 1,2-dichlorobenzene (39g, weight ratio 1:3.9) and dissolved at 55 for 60 minutes made it27.7 g (8 equivalents) of sulfuric acid was added to the reaction solution and stirred for 15 hours until the reaction was completed at 50°C.After completion of the reaction, after cooling to room temperature, 100 ml of water was added to the reaction solution, and extraction was performed to remove 1,2-dichlorobenzene.In the same manner as in the work-up procedure of Example 1, mirtazapine 9.35 g (HPLC: 99.2%) yield: 99.8% was obtained as a slightly dark white solid.
