Abstract:
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.

Claim (Index 4):
The amine solvate of the compound of formula (I) according to  claim 3 , wherein the X-ray powder diffraction pattern of the diethylamine solvate of the compound of formula (I) comprises peaks at diffraction angle (2\u03b8) of 13.78\u00b10.2\u00b0, 17.02\u00b10.2\u00b0, 16.48\u00b10.2\u00b0, and 12.46\u00b10.2\u00b0; preferably further comprises peaks at diffraction angle (2\u03b8) of 23.94\u00b10.2\u00b0, 18.74\u00b10.2\u00b0, 18.76\u00b10.2\u00b0, 15.72\u00b10.2\u00b0, and 20.68\u00b10.2\u00b0; more preferably further comprises peaks at diffraction angle (2\u03b8) of 10.82\u00b10.2\u00b0, 21.58\u00b10.2\u00b0, 23.26\u00b10.2\u00b0, 25.16\u00b10.2\u00b0, 25.58\u00b10.2\u00b0, and 24.26\u00b10.2\u00b0; and most preferably the X-ray powder diffraction pattern of the diethylamine solvate of the compound of formula (I) comprises substantially the same peaks at diffraction angles (2\u03b8) as shown in Table 1.
