Reaction Steps

To a solution of 2-(5-chloro-2-fluorophenyl)-4-iodo-6,7-dihydrofuro[3,2-d]pyrimidine (106 mg, 0.28 mmol, 1 eq) in dioxane (5 ml) was added Pd(OAc)2 (3 mg, 0.01 mmol, 0.05 eq) followed by BINAP (13 mg, 0.02 mmol, 0.075 eq), 4-amino-3-picoline (40 mg, 0.37 mmol, 1.3 eq) and Cs2CO3 (138 mg, 0.42 mmol, 1.5 eq). The reaction mixture was heated to 80° C. for 15 h. The reaction mixture was cooled to r.t. and filtered through Celite® and the crude material was purified by flash column chromatography (4:1/ethyl acetate:hexane-100% ethylacetate) to afford [2-(5-chloro-2-fluorophenyl)-6,7-dihydrofuro[3,2-d]pyrimidin-4-yl]-(3-methyl-pyridin-4-yl)-amine, i.e. compound of formula (39) (30 mg, 30%) as a white solid.
