Procedure

To a solution of 2-(azetidin-3-yloxy)-3-(3,6-dihydro-2H-pyran-4-yl)pyridine hydrochloride (see PREPARATION P26.1; 100 mg, 0.45 mmol), pyrimidine-4-carboxylic acid (55 mg, 0.45 mmol) and triethylamine (96.13 mg, 0.95 mmol) in CH2Cl2 (10 mL) was added 4-Dimethylaminopyridine (DMAP) (55 mg, 0.47 mmol) and propyl phosphonic anhydride (500 mg, 0.9 mmol). The reaction mixture was stirred at room temperature for overnight. Then the reaction mixture was concentrated and the crude product was purified by silica gel column chromatography to give the desired compound (48 mg, 0.16 mmol, yield 66%). [M+1]: 339. IC50 (uM): 0.99.
