Trifluoroacetic acid → 3-[4-(dimethylamino)-7-(hydroxymethyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl]benzyl trifluoroacetate

Participants

Reaction Steps

A solution of {3-[4-(dimethylamino)-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-5-yl]phenyl}methanol (C26) (397 mg, 0.996 mmol) in trifluoroacetic acid (10 mL) was stirred at room temperature for 2 hours. The reaction mixture was concentrated in vacuo to provide the product (400 mg) as a brown oil. This material was taken directly into the following step. LCMS m/z 395.1 [M+H+].
