2-氟-3-甲氧基溴苄

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The subtitle compound was prepared as a white solid by the method of Example 39 step i) using 1-(bromomethyl)-2-fluoro-3-methoxybenzene (4.5 g), 2-mercaptopyrimidine-4,6-diol (2.96 g) and potassium hydroxide (1.15 g). Yield: 5.0 g.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Triphenylphosphine (11.1 g) was added to a solution of the subtitle product of step ii) (5.0 g) in DCM (200 ml) followed by the portionwise addition of carbon tetrabromide (14.0 g). The reaction was stirred for 4 h before the addition of further triphenylphosphine (2.0 g) and carbon tetrabromide (2.0 g) and stirring maintained for 1 h. The mixture was concentrated to 30 ml volume and diluted in Et2O (300 ml). The solid precipitate was filtered and washed with Et2O (3×) and the filtrate concentrated in vacuo. The residue was purified by column chromatography (10% Et2O/iso-hexane) to afford the subtitle compound as a clear oil. Yield: 5.2 g. maintained for 1 h The mixture was concentrated to 30 ml volume diluted in Et2O (300 ml) The solid precipitate was filtered washed with Et2O (3×) the filtrate concentrated in vacuo The residue was purified by column chromatography (10% Et2O/iso-hexane)
