2-Amino-2-methyl-1-propanol → HCID 60055735, compound

Participants

Reaction Steps

A solution of 2-(5-methoxy-1-methyl-1H-indol-3-yl)-1H-pyrrolo[2,3-b]pyridine-4 carboxylic acid [32 mg, Example 41(a)] in dry dimethylformamide (10 mL), under nitrogen, was treated with diisopropylethylamine (35 μL) followed by O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (38 mg). After stirring at room temperature for 1 hour this mixture was treated with a solution of 2-amino-2-methyl-1-propanol (10.5 μL) in dry dimethylformamide (1 mL) and stirring was then continued for a further 2 hours. The reaction mixture was evaporated and the residue was treated with saturated aqueous sodium bicarbonate solution (15 mL). This mixture was stirred for 1 hour and the resulting yellow solid was filtered, then washed well with water and then dried at 100° C. under vacuum to give the title compound (34 mg) as a yellow solid, m.p. 210-212° C.
