Versuchsvorschrift

To a solution of 6-bromopyridin-2-amine (1.24 g, 7.17 mmol) in THF (10.00 mL) was added 60% NaH (294 mg, 7.35 mmol). The mixture was stirred for 30 min until cessation H2 evolution. The resulting dark green solution was added by syringe to a suspension of 8A (800 mg, 2.453 mmol) in DMF (10 mL). The reaction mixture was stirred at room temperature overnight, and then added to ice water. The brown solid was collected by filtration and dried under vacuum to give 17A (1.125 g, 89%) MS (m+1)=462. HPLC Peak Rt=3.696 minutes (Chromolith column 4.6×50 mm eluting with 10-90% aqueous methanol over 4 minutes containing 0.1% TFA, 4 mL/min, monitoring at 220 nm).
