Procedure

To a solution of 2-(N-(2-fluorobenzyl)-N-methylamino)-ethanol (Step. B, 7.51 g, 41 mmol) in dry toluene (50 ml) was added thionyl chloride (16 ml). The reaction mixture was stirred at room temperature for 16 hours and concentrated. The crude mixture was diluted with chloroform and washed with aq NaHCO3, water and brine. The organic layer was dried over Na2SO4, filtered and concentrated to provide the title compound which was used without further purification.
