(4-chloro-2-cyclopentyloxyphenyl)boronic acid

Conditions: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A batch with crude crude 4-chloro-N-{3-[(methylsulfonyl)methyl]phenyl}-1,3,5-triazin-2-amine (175 mg), [4-chloro-2-(cyclopentyloxy)phenyl]boronic acid (141 mg; 0.59 mmol; Combi-Blocks Inc.) and [1,1′-bis(diphenylphosphino)ferrocene]palladium dichloride (72 mg; 0.09 mmol) in 1,2-dimethoxyethane (2.0 mL) and 2M solution of potassium carbonate (0.6 mL) was degassed using argon. The batch was stirred under argon for 60 minutes at 100° C. After cooling the batch was diluted with ethyl acetate. The organic phase was filtered using a Whatman filter and concentrated. The residue was purified by preparative HPLC. After cooling the batch The organic phase was filtered filter concentrated The residue was purified by preparative HPLC
