반응 단계

NaH (0.1 g, 60% in oil, 2.56 mmol) was added in one portion to a stirred and cooled (0° C.) solution of the product of Example 7D (0.48 g, 1.42 mmol) and 6-chloro-nicotinonitrile (0.35 g, 2.56 mmol) in tetrahydrofuran (7 ml) and 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (7 mL). After the addition, the solution was warmed to room temperature and stirred for another five hours. The dark brown reaction mixture was cooled (0° C.), quenched with acetic acid (0.1 mL), and partitioned with diethyl ether and water. The organic phase was washed with water and brine, dried (MgSO4), filtered, and evaporated. The residue was purified over silica gel using 5-80% ethyl acetate in hexanes to give the titled product as a solid.
