Reaction Steps

A scintillation vial was charged with 4-amino-2-ethylthiazolo[4,5-c]quinolin-7-ol (1.0 eq., 1.0 mmol) and anhydrous DMF (2 mL). The mixture was warmed until a solution was obtained. An additional amount of DMF (1 mL) was added. To this stirred orange solution was added cesium carbonate (3.0 eq., 3.0 mmol) and a solution of 3-(2-bromoethyl)indole (1.0 eq., 1.0 mmol) dissolved in DMF (2 mL). Additional DMF (1 mL) was used to rinse the vial. The vial was capped and heated to 60° C. overnight. The reaction was monitored by HPLC. The reaction was quenched by adding the reaction mixture drop-wise to water (60 ml) with stirring. A precipitate formed. The solid was collected by vacuum filtration. The solid was then dissolved in methanol and adsorbed onto silica gel (6 g) for purification by HPFC (0-15% CMA in chloroform, 1440 mL). Pure fractions were combined and concentrated; the resulting solid was recrystallized from methanol to provide a peach colored crystalline solid, mp 218-220° C. MS (APCI) m/z 389 (M+H)+.
