Reaction Conditions:
with methanol;sodium methylate in toluene at 113; under 13501.4 Torr; for 0.00555556 h;Temperature;Pressure;
Steps:
1; 2; 3 Synthesis of sotagliflozin in toluene
Sotagliflozin was synthetized in an intensified reactor at 113°C under a pressure of 8 bar.The reactor was fed with the solution of compound (A) in 10 Volumes of toluene with a flow of 1194.6 g/h and the methanolic solution of MeONa (0.6 equivalent of MeONa and 15 equivalents of MeOH) with a flow of 114.6 g/h, which were preheated at 113°C.The time of residence in the reactor was 20 seconds.The system was maintained at a pressure of 8 bar.Sotagliflozin was synthetized with a yield of 99.7%.Aqueous washing, dehydration, crystallization, filtration, washing, drying were performed according to example 2.An XRPD (X-ray diffraction) analysis confirmed that Form II of sotagliflozin was obtained.
