To a solution of (1-(5-bromo-4-((1-(quinolin-2-yl)azetidin-3-yl)oxy)pyrimidin-2-yl)piperidin-4-yl)methanol (see PREPARATION P7.1; 115 mg, 0.25 mmol), 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (52.5 mg, 0.25 mmol) and K3PO4 (100 mg, 0.5 mmol) in 1,4-dioxane (10 mL) and H2O (2 mL) was added Pd(dppf)Cl2 (15 mg, 0.02 mmol) then the reaction mixture was stirred at 110° C. under N2 atmosphere overnight. The reaction mixture was filtered through CELITE® and washed with CH2Cl2 (30 mL). The filtrate was concentrated and the crude product was purified by silica gel column to give (1-(5-(3,6-dihydro-2H-pyran-4-yl)-4-((1-(quinolin-2-yl)azetidin-3-yl)oxy)pyrimidin-2-yl)piperidin-4-yl)methanol (100 mg, 0.21 mmol, yield 84%). ESI-MS (M+1): 474 calc. for C27H31N5O3 473.
