2-chloro-5-(5-(chloromethyl)-1,3,4-oxadiazol-2-yl)-N-isopropylpyridin-4-amine (46) (60 mg, 0.2 mmol) was taken in a rbf, added morpholine (4 mL) to the rbf followed by the addition of potassium iodide (0.2 mmol), stirred the reaction mixture overnight at room temperature. The reaction mixture was concentrated under reduced pressure to remove excess of morpholine. The crude material obtained was taken to next step as such, without purification. LC/MS: Purospher@star RP-18, 4×55 mm, 3 μm; Solvent A=10% ACN: 90% H2O: 20 mM NH4OAc; Solvent B=90% ACN: 10% H2O: 20 mM NH4COOAc; gradient 0-100% B over 1.5 min (3.2 min run time); retention time: 1.608 min; LCMS (ES-API), m/z 338.2 (M+H).
