Process for the crystallization of (r)- or (s)-lansoprazole |
| abstract |
The present invention is crystallized from a C 1-4 alkyl acetate solution containing (R) -lansoprazole or (S) -lansoprazole at a concentration of about 0.1 g / mL to about 0.5 g / mL at a temperature of about 0 ° It relates to a process for the preparation of crystals of (R) -lansoprazole or (S) -lansoprazole, which comprises trituration. According to the production method of the present invention, crystals of (R) -lansoprazole or (S) -lansoprazole having excellent storage stability can be efficiently produced on an industrial scale. |
