반응 단계

As a demonstrative example, a cocrystal comprising a neutral API is described in this example. Cocrystals of nabumetone (a neutral API) and 2,3-naphthalenediol were prepared as follows. A 4.01 g sample of 2,3-naphthalenediol and 5.7 g of nabumetone were dissolved in 50 mL of nitromethane with heating. A solid was formed as the solution cooled and was allowed to stand overnight. The solid was filtered from the remaining solvent and dried in the air to yield 6.61 g (68%) of nabumetone:2,3-naphthalenediol (1:1) cocrystal.
