4-(2-Pyrrolidin-1-ylethoxymethyl)piperidine (0.10 g, 0.47 mmol), triethylamine (0.089 mL, 0.63 mmol) and 4-chloro-2-cyclopropyl-5-(2-methoxyphenyl)thieno[2,3-d]pyrimidine (0.10 g, 0.32 mmol) were combined and heated to 50° C. in ethanol (10 mL) overnight. The solvent was removed at reduced pressure. The residue was taken up in DCM (20 mL), washed with water (20 mL) and the organic dried over Na2SO4 and concentrated at reduced pressure. The resulting residue was purified by flash chromatography, eluting with a gradient of DCM to 90/10/1 DCM/MeOH/NH4OH to afford 2-cyclopropyl-5-(2-methoxyphenyl)-4-[4-(2-pyrrolidin-1-ylethoxymethyl)-1-piperidyl]thieno[2,3-d]pyrimidine (0.03 g). LCMS: purity 100%, RT=3.62 min, M+1=493.1
