実験手順

Of the compound from Example 1, 45 mg (77 μmol) and 40 mg (348 μmol) of indium powder were admixed in 0.5 ml of THF with 42 μl of conc. hydrochloric acid, and the mixture was stirred at RT for 2 h. Then the mixture was purified by preparative HPLC (Method 10). The product-containing fractions were admixed with 2 ml of 1N hydrochloric acid and concentrated on a rotary evaporator. Drying in an HV gave 21 mg (46% of theory) of the title compound as a diastereomer mixture.
