Participants

Reaction Steps

2-(Tetrahydro-2H-pyran-2-yl)-6-[3-(tetrahydro-2H-pyran-2-yloxy)phenyl]-2H-indazol-4-amine (50 mg, 0.127 mmol) was dissolved in DCM (1 ml) and DIPEA (0.111 ml, 0.635 mmol) and cyclohexanecarbonyl chloride (45 mg, 0.254 mmol) were added. The reaction was stirred at RT for 1 h. 2 M Sodium hydroxide (aq) (2 ml) was added and the reaction stirred at RT for 1 h, before the organic layer was passed through a hydrophobic frit. The aqueous layer was washed several times with DCM, which was passed through a hydrophobic frit. The combined organic layers were evaporated under a stream of nitrogen. The residue was dissolved in MeOH (2 ml) and 4 M HCl in dioxane was added (2 ml). The reaction was stirred at RT for 1 h. The solvent was removed under a stream of nitrogen and the residue was dissolved in DMSO:MeOH (1:1, v/v) and purified by MDAP (Method B). The residue was dissolved in 1,4-dioxane:water and freeze dried to produce the title compound.
