Reaktionsschritte

To a solution of the product from Example 70, Part B (300 mg, 1.3 mmol) and 2-methyl-2-pentene (8 ml) in tert-butanol (32 ml) was added a solution of sodium chlorite (1.36 g, 0.12 mmol) in H2O (12 ml) containing sodium dihydrogen phosphate (1.07 g, 8.9 mmol) and the mixture was stirred vigorously for 20 min at room temperature. Solvents were concentrated in vacuo and the residue was diluted with H2O, extracted with EtOAc (3×), extracts combined, dried (Na2SO4), and concentrated in vacuo to give the title compound (180 mg, 56%).
