| abstract |
(57) [Problem] To provide a method for producing a crystal of (R) -lansoprazole or (S) -lansoprazole having excellent storage stability. SOLUTION: (R) -lansoprazole or (S) Lansoprazole at a concentration of about 0.1 to about 0.5 g / ml from a C 1-4 alkyl acetate solution to about 0 (R) characterized in that it is crystallized at a temperature of about 35 ° C. -A method for producing crystals of lansoprazole or (S) -lansoprazole. 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 a large industrial scale. |
