    摘要: A crystallization process for forming a stable crystal of N-(3,3-dimethylbutyl)-APM, which comprises using either water or a mixture of water with a lower alcohol as the crystallizing solvent and controlling the crystallization point to 30° C. or above; and another crystallization process therefor, which comprises using either water or a mixture of water with a lower alcohol as the crystallizing solvent and using as the seed crystal a crystal of N-(3,3-dimethylbutyl)-APM exhibiting peculiar peaks of diffracted X-ray at least at diffraction angles (2θ, CuKα ray) of 6.0°, 24.8°, 8.2° and 16.5° to thereby crystallize the above objective crystal preferentially. These crystallization processes enable the constant formation of stable crystals of N-(3,3-dimethylbutyl)-APM at a low cost.

    摘要: For example, N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine methyl ester (A-type crystal) showing characteristic peaks in diffractive X-ray at diffraction angles (2&thgr;, CuK&agr; ray) of at least 6.0°, 24.8°, 8.2° and 16.5° is dried to its water content below 3% by weight. The crystal thus dried is a novel crystal (C-type crystal) of N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine methyl ester excellent in dissolution rate, and when measured by powder X-ray diffractometry, this crystal shows characteristic peaks in diffractive X-ray at diffraction angles (2&thgr;, CuK&agr; ray) of at least 7.1°, 19.8°, 17.3° and 17.7°. The dissolution rate (solubility) of the C-type crystals is further improved by converting the crystals into granules.
