Procedure

1-Chloro-N,N,2-trimethyl-1-propen-1-amine (0.042 ml) was added to 6-methyl-2-pyridinecarboxylic acid (44 mg) in DCM (1 ml). The reaction was stirred at RT for 20 mins. N-[5-(4-Amino-1-methyl-1H-indazol-6-yl)-2-chloro-3-pyridinyl]methanesulfonamide (75 mg) in DCM (2 ml) was added and the reaction stirred for 30 mins. Approximately 4 ml saturated sodium bicarbonate (aq) was added followed by DCM (3 ml). The reaction was stirred vigorously. The DCM was passed through a hydrophobic frit then evaporated to dryness. The residue was dissolved in DMSO:methanol (1 ml, 1:1, v/v) and purified by MDAP (method E). The pure fraction was evaporated to dryness to give title compound (6 mg)
