1-(3-Methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)guanidine (86 mg, 0.28 mmol) and potassium carbonate (77 mg, 0.56 mmol) in EtOH (7 mL) were heated to 60° C. for 10 min followed by the addition of 3-(2-(3,5-dimethyl-1H-pyrazol-1-yl)propanoyl)dihydro-2H-pyran-4(3H)-one (70 mg, 0.28 mmol). The reaction was stirred over night. Solvent was evaporated and the crude product was taken up in DCM and washed with water. The product was purified on a prepHPLC yielding 4-(1-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl)-N-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)-7,8-dihydro-5H-pyrano[4,3-d]pyrimidin-2-amine (5.00 mg, 3.89%).
