3-Methyl-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]butan-1-ol → 3-Methyl-3-[4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]butan-1-ol

Reaction Steps

A solution of 3-methyl-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]butan-1-ol (13.8 g, 0.0344 mol) in TFA (20 mL) was stirred for 1 hour. The mixture was then concentrated in vacuo and the residue was stirred for 2 hours in a mixture of methanol (30 mL), ammonium hydroxide (30 mL), and ethylenediamine (8 mL). The mixture was then concentrated, and the residue was diluted with water and extracted with several portions of 15% IPA/CH2Cl2. The combined extracts were dried over sodium sulfate and concentrated in vacuo to give 20 g of white solid. The solid was triturated with ether and the product was isolated by filtration to give the product as a white solid (7.75 g, 83%).
