Provided is a method of producing optically active 1-methyl-3-phenylpiperazine of the formula (11) or salt thereof, comprising the following steps 1 to 4, or steps 5 to 7 and step 4, and a method of producing optically active mirtazapine via this method.
A solvent in which dichloromethane is mixed with alcohol as a poor solvent is used for preparing a dope. Alcohol is supplied to the dope in a inline pipe to mix with a static mixer, such as a casting dope in which a composition of alcohol is increased. The temperature of the rotary drum is adjusted to −7° C. The casting dope is fed from a casting die to the rotary drum so as to form a casting film whose thickness is 40 μm. Since the content of alcohol is high and a storage modulus of the cooled casting film is at least 150 thousands Pa, the peeling defect does not occur, and the stretch is reduced as far as possible. A gel-like film is dried by a tenter type drying device, and stretched such that the stretch ratio is at most 110%. The produced film is thin and excellent in a surface condition and optical isotropy.
