Thionyl Chloride → Benzo[1,3]dioxol-5-yl-[6-(4-chloromethyl-phenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl]-amine

Participants

Reaction Steps

To a suspension of 1.83 g of {4-[4-(benzo[1,3]dioxol-5-ylamino)-7H-pyrrolo[2,3-d]pyrimidin-6-yl]-phenyl}-methanol in 56 ml of dioxane/acetonitrile 1:1 under N2-atmosphere, 3.1 ml of thionylchloride are added. After 16 h stirring, the suspension is diluted with ethyl acetate and NaHCO3-solution. The aqueous layer is separated off and extracted twice with ethyl acetate. The organic phases are washed with water and brine, dried (MgSO4) and concentrated to yield the title compound; MS-ES+: (M+H)+=379; HPLC (conditions see Examples 67-78) tR=11.4 min.
