Reaction Steps

To a solution of (4-(4-chloro-2-fluorophenyl)-2-methylpyridin-3-yl)methanol (70 mg, 0.278 mmol) in tetrahydrofuran (3 mL) at 0° C. was added NaH (33.4 mg, 0.834 mmol) portionwise. The solution was allowed to warm to room temperature and stirred for 5 h. The reaction mixture was quenched with ice cold water and diluted with EtOAc (15 mL). The organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure to afford 8-chloro-4-methyl-5H-chromeno[3,4-c]pyridine (0.11 g, 0.475 mmol, 73% yield) as a brown solid. LCMS (ESI) m/e 232.00 [(M+H)+, calcd for C13H12ClNO 232.01]; LC/MS retention time (Method G): tR=1.00 min.
