Reaction Steps

169 mg (1 mmol) 3-[(2-Fluoro-ethyl)-methyl-amino]-phenol are dissolved in 4 mL DMF and cooled below 10° C. 0.101 mL (1.1 eq.) POCl3 are added dropwise over the course of one minute, the reaction mixture is stirred 10 minutes at room temperature, then heated to 90° C. for 30 minutes. The reaction mixture is allowed to cool to 30° C. and cautiously treated with a slow addition of 8 mL saturated aqueous sodium bicarbonate solution. The desired product is extracted with ethyl acetate and saline, the organic phase dried over sodium sulfate and evaporated to yield 130 mg (66%) crude product as a slightly brownish oil.
