Procedure

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of N-(2-((4-acetylthiazol-2-yl)methyl)-2H-1,2,3-triazol-4-yl)-2-methyl-5-(m-tolyl)oxazole-4-carboxamide (example 75 from WO 2009/077990; 50 mg, 0.12 mmol) in CH2Cl2 (1.1 mL) was treated at 0° C. with AlMe3 (0.3 mL of a 1.0M solution in heptane, 0.3 mmol) and the resulting mixture was stirred for 2 h at 0° C. The reaction mixture was carefully poured into a sat. aq. solution of ammonium chloride (5 mL) and diluted with CH2Cl2 (10 mL). 1N HCl (5 mL) was then added. The layers were separated and the org. phase was dried over Na2SO4, filtered and the solvents were removed under reduced pressure. Purification of the residue by FC (1:1 hept-EA) gave the title compound as a colorless oil: TLC: rf (1:1 hept-EA)=0.20. LC-MS-conditions 02: tR=0.88 min, [M+H]+=438.94.
