Procedure

To a solution of (R)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(1-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-6-fluoro-2-(4-hydroxy-2-methylbutan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide containing some 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6-fluoro-2-(4-hydroxy-2-methylbutan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide (315 mg, 0.55 mmol) in methanol (3 mL) and water (0.3 mL) was added p-TsOH.H2O (21 mg, 0.11 mmol). The mixture was heated at 80° C. for 30 minutes. The reaction was partitioned between ethyl acetate and water and the aqueous layer was extracted with ethyl acetate twice. The combined organic layers were washed with saturated. NaHCO3 solution and brine and dried over MgSO4. After the removal of solvent, the residue was purified by column chromatography (20-80% ethyl acetate-hexanes) to provide (R)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(1-(2,3-dihydroxypropyl)-6-fluoro-2-(4-hydroxy-2-methylbutan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide (92 mg, 31%).
