Reaction Steps

Using similar reaction conditions as described in step-i of example-82A, 3-(1-phenethyl-1H-pyrazol-4-yl)-5-(6-(piperazin-1-yl)pyridin-3-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (product of step 2 of example 140) (85 mg, 0.14 mmol) was alkylated using (S)-2-methyloxirane (10 mg, 0.169 mmol), DIPEA (22 mg, 0.169 mmol) and ethanol (3 mL) to get 80 mg (86%) of the titled compound. MS: m/z=662.3 (M+1).
