Hydrochloric Acid → 2-Chloro-7-(pentan-3-yl)-7H-pyrrolo[2,3-d]pyrimidine-6-carbaldehyde

Participants

Reaction Steps

To a solution of 2-chloro-6-diethoxymethyl-7-(1-ethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidine (67 mg, 0.2 mmol) in 1,4-dioxane (0.7 mL) is added conc. HCl (0.2 mL) at ambient temperature. The reaction mixture is stirred for 30 min, then neutralized with 2N NaOH aqueous solution and saturated NaHCO3 aqueous solution. The mixture is extracted with EtOAc. The extracts are washed with brine, dried over Na2SO4, filtered and concentrated in vacuo to give 54 mg of 2-chloro-7-(1-ethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidine-6-carbaldehyde as a yellow solid. The crude product is used as it is.
