Versuchsvorschrift

To an argon purged round bottom flask fitted with a condenser and magnetic stirbar containing 49 (105 mg, 0.442 mmol) was added lithium aluminum hydride (34 mg, 0.896 mmol) followed by absolute THF (5 mL). A small amount of gas was produced. Once no more bubbling occurred, the reaction was transferred to an oil bath heated to 75° C. The reaction was stirred at this temperature for 18 hrs. The reaction was then cooled to room temperature. The reaction was quenched with water (0.1 mL), 3N NaOH (0.1 mL) and water (0.3 mL) sequentially, followed by filtration through a celite plug. The plug was washed with THF and the filtrate concentrated to afford a yellow oil, compound 50 (106 mg, 99%). 1H NMR (DMSO) δ 10.95 (br s, NH), 7.74 (s, 1H), 7.32-7.31 (d, J=2.4 Hz, 1H), 7.30-7.27 (d, J=8.4 Hz, 1H), 7.08-7.05 (d, J=8.1 Hz, 1H), 6.14 (s, 1H), 3.77 (s, 2H), 3.29 (s, 2H), 3.06-3.05 (d, J=2.7 Hz, 2H), 2.57-2.56 (d, J=4.5 Hz, 2H), 2.51-2.50 (d, J=1.2 Hz, 2H), 2.29 (s, 3H), 1.75 (br s, 2NH).
