反応条件: temp:-10.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of 3,5-difluoro-4-methoxybenzylamine (8.7 g, 0.05 mole) and triethylamine (15.5 ml, 0.11 mole) in 50 ml of tetrahydrofuran was added dropwise to a solution of thiophosgene (4.2 ml, 0.055 mole) in 50 ml of tetrahydrofuran with cooling to -10° C. over a period of twenty minutes. The mixture was stirred at 25° C. for 2.75 hours and then filtered. The filtrate was treated with charcoal, filtered, and evaporated to an oil. The oil was diluted with hexane:ethyl acetate (90:10) and purified on a flash silica column using hexane:ethyl acetate (90:10) as the eluant to yield 9.2 g (79%) of 3,5-difluoro-4-methoxybenzyl isothiocyanate. filtered The filtrate was treated with charcoal filtered evaporated to an oil The oil was diluted with hexane:ethyl acetate (90:10) purified on a flash silica column
