| titleOfInvention | Method for producing benzoic acid derivative crystals |
| abstract | 4-[(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl) carbamoyl] benzoic acid crystal having a single endothermic peak at around 233 ° C. in differential scanning calorimetry Wherein the crystal of 4-[(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl) carbamoyl] benzoic acid is treated with a mixture of water and ethanol. A method comprising the step of recrystallizing. A type II crystal that is stable against physical impact can be selectively produced, and the obtained crystal does not contain highly toxic hexane as a residual solvent, and thus can be suitably used as an active ingredient of a drug. . |
