Reaction Steps

Tert-butyl 3-(5-(2,5-difluorophenyl)-2-(3-hydroxyphenyl)-3-(5-methyl-1,3,4-thiadiazol-2-yl)-2,3-dihydro-1,3,4-thiadiazol-2-yl)propylcarbamate (51 mg, 0.093 mmol) was weighed into a 25 mL flask, and dissolved in 7 mL of Et2O/DCM (1:1). HCl-Et2O (1.8 mL, 1.863 mmol) was added, and the reaction mixture was stirred at room temperature for 2 hours. An additional 20 equivalents of HCl-Et2O was added and the reaction mixture was stirred an additional 2 hours. The crude reaction mixture was concentrated in vacuo to afford a yellow solid. The solid was then purified by flash column chromatography (10-40% MeOH/DCM), affording the desired product (31 mg, 74% yield) as a yellow foam. MS ESI (+) m/z 448 (M+1) detected; 1H NMR (400 MHz, DMSO-D6) δ 7.90 (m, 1H), 7.51 (m, 2H), 7.19 (m, 1H), 6.84 (m, 2H), 6.74 (m, 1H), 3.21 (m, 1H), 2.98 (m, 1H), 2.89 (m, 2H), 2.56 (m, 3H), 2.61 (m, 1H), 2.10 (m, 1H), 1.60 (m, 1H).
