Reaction Steps

To a solution of tert-butyl 2-(2-(2-(tert-butyldiphenylsilyloxy)ethyl)-5-(2,5-difluorophenyl)-2-phenyl-1,3,4-thiadiazol-3(2H)-yl)-6,7-dihydrothiazolo[5,4-c]pyridine-4(4H)-carboxylate (prepared according to Example 26, Steps A-D; 0.090 g, 0.113 mmol) in 1 mL of 1,4-dioxane was added 4M HCl/dioxane (1 mL). The mixture was stirred at room temperature for 16 hours then treated with 4M HCl/dioxane (2 mL) and stirred for a further 3 hours. Water (1 mL) was added and the mixture was stirred for 16 hours then concentrated and dried in vacuo. The residue was triturated with diethyl ether, filtered, washed with ether and dried in vacuo to afford the desired product as an orange/yellow solid, 0.023 g, 38%. MS ESI (+) m/z 459 (M+1) detected; 1H NMR (400 MHz, CDCl3) δ 7.59 (m, 1H), 7.46 (m, 2H), 7.33 (m, 3H), 7.07 (m, 2H), 4.12 (m, 1H), 3.95 (m, 1H), 3.87 (m, 2H), 3.65 (m, 2H), 3.05 (m, 2H), 2.84 (m, 1H), 2.43 (m, 2H) ppm.
