Reaction Steps

3-(Ethylamino)-1,1,1-trifluoro-2-({[1-(4-fluorophenyl)-1H-indazol-4-yl]amino}methyl)-2-propanol (25 mg, 0.063 mmol) was dissolved in anhydrous dichloromethane (0.15 ml). N,N-diisopropylethylamine (0.011 ml, 0.13 mmol) was then added followed by 2,6-dimethylbenzoyl chloride in DCM (10.6 mg, 0.065 mmol as a 100 μl aliquot of 80.8 mg in 0.76 ml DCM) and the mixture stirred at room temperature overnight. The mixture was diluted with dichloromethane, washed successively with aqueous sodium bicarbonate and water and then dried through a hydrophobic frit and evaporated and the crude product purified by mass directed autopreparation (System B). Product containing fractions were partitioned between dichloromethane and aqueous sodium bicarbonate. The aqueous layer was re-extracted with dichloromethane and the combined organic extracts were washed successively water and brine, dried through a hydrophobic frit and evaporated in vacuo to give the title compound (13.1 mg).
