Amine solvate of sodium-glucose linked transporter inhibitor, and preparation method and application thereof

摘要

Disclosed are an amine solvate of a sodium-glucose linked transporter (SGLT) inhibitor, and a preparation method and application thereof. The SGLT inhibitor is (1S,2S,3S,4R,5S)-5-(3-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)methyl)-4-ethylbenzyl)-1-(hydroxymethyl)-6,8-dioxabicyclo[3.2.1]octane-2,3,4-triol. Further provided is a crystalline compound of the amine solvate, a pharmaceutical composition comprising the amine solvate, and an application of the amine solvate in preparing an SGLT-inhibiting pharmaceutical product.
