To a solution of 5-fluoropyridin-2-amine (20.63 mg, 0.184 mmol) in DMF (1 mL) was added 60% NaH (7.36 mg, 0.184 mmol). The mixture was stirred for 10 min until cessation of H2 evolution. 8A (24 mg, 0.074 mmol) was added. The mixture was stirred at room temperature overnight. Water was added, and the yellow solid was collected by filtration and dried to give 16A (25.2 mg, 57%). [M+H]=4 01. HPLC Peak Rt=3.345 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.).
