실험 절차

6-Methyl-2-pyridinecarboxylic acid (43 mg) was dissolved in DCM (2 ml) and 1-chloro-N,N,2-trimethyl-1-propen-1-amine (0.042 ml) was added. The reaction was stirred for 15 mins. N-{5-[4-Amino-1-(phenylsulfonyl)-1H-indazol-6-yl]-2-chloro-3-pyridinyl}methane sulfonamide (100 mg) in DCM (4 ml) was added and the reaction left at RT. The reaction was evaporated to dryness. IPA (3 ml) was added to the residue followed by 2M NaOH (aq) (3 ml) and the reaction was left overnight. The solution was neutralised using 2M HCl (aq) and then concentrated. The precipitate that formed was filtered then DMSO was added to the precipitate. Attempts to filter the solid failed so the reaction was blown down under a stream of nitrogen. The residue was redissolved in DMSO (0.5 ml) and purified by MDAP (method E). The pure fraction was evaporated to dryness to give title compound (40 mg).
