Participants

Reaction Steps

Dissolve 2-(4-methoxyphenyl)-N-(2-{[7-(4-methoxy-2,6-dimethylphenyl)-2,5-dimethylpyrrolo[2,3-e]pyrimidin-4-yl]aminoethyl)acetamide in anhydrous THF (5 mL) and stir under N2. Add borane-dimethylsulfide complex (0.2 mL, 10.0 M in THF) and heat to reflux for 14 h. Quench by addition of N,N′-dimethyl-1,2-ethylenediamine (0.21 mL) in MeOH (5 mL) and stir for 1 h at ambient temperature. Concentrate under reduced pressure and purify the residue by preparative TLC, eluting with 10% MeOH in CH2Cl2. Dissolve the residue in a minimum amount of MeOH then add HCl in EtOAc (2 mL) and triturate with Et2O to obtain the title compound as a solid (HCl salt).
