Reaction Steps

A mixture of 5-trifluoromethyl-[1,4]diazepane hydrochloride (1.17 g; 4.83 mmol; 1.2 eq.), sodium carbonate decahydrate (2.13 g; 20.14 mmol; 5 eq.) and 2-fluoro-benzaldehyde (500 mg; 4.03 mmol; 1 eq.) in DMSO (20 mL) and water (20 mL) was stirred at 160° C. for 4 hours. The solution was diluted EA and the organic layer washed with water (3×) then brine (2×), dried over magnesium sulfate and concentrated in vacuo. Purification by column chromatography (15% to 33% EA in heptanes) afforded the title compound (350 mg, 32%) as a yellow oil. HPLC (max plot) 97.9%; Rt 5.23 min.
