Abstract
The present invention provides novel crystal forms of arylalkylamine compounds. Specifically, the novel crystal forms of 4-(3S-(1R-(1-naphthyl)ethylamino)pyrrolidin-1-yl)phenylacetic acid have excellent stability and therefore are useful as pharmaceutical ingredients. The present invention also provides industrially advantageous processes for producing the arylalkylamine compounds.
