Participants

Reaction Steps

In a microwave vial, 1-benzenesulfonyl-5-chloro-3-(2-methanesulfonyl-pyrimidin-5-ylmethyl)-1H-pyrrolo[2,3-b]pyridine (132, 12 mg, 0.026 mmol) was mixed with 600 μL of N-methylpyrrolidinone and (S)-1-(4-fluoro-phenyl)-ethylamine (133, 25.2 mg, 0.18 mmol). The reaction was irradiated at 200° C. for 40 minutes in microwave, then potassium hydroxide (500 μL, 4.00 M in water) was added and the reaction irradiated at 90° C. for 10 minutes in microwave. The reaction was neutralized with the addition of 120 μL of acetic acid, solvents were removed under vacuum, and the resulting material was dissolved in 400 μL of dimethyl sulfoxide for purification by HPLC. The desired compound was purified on Phenomenex C18 column (50 mm×10 mm ID) with mobile phase A of 0.1% trifluoroacetic acid in water, mobile phase B of 0.1% trifluoroacetic acid in acetonitrile, 20-100% B over 16 minutes at a flow rate of 6 mL/min. Appropriate fractions were collected and solvents removed under vacuum to provide the desired compound. MS (ESI) [M+H′]′=381.9.
