Methyl 6-cyano-7-fluoro-3,4-dihydro-2H-chromene-4-carboxylate (from Example 3, Step E; 28 mg, 0.12 mmol) was diluted with acetonitrile (1 mL) followed by the addition of K2CO3 (49 mg, 0.36 mmol) and iodomethane (0.023 mL, 0.36 mmol). The reaction was then heated at 60° C. for 1 hour, then cooled and NaH (8.6 mg, 0.36 mmol) was added. The reaction was deemed complete by LC. The reaction was loaded onto a Biotage 25 samplet and purified running a gradient 5% ethyl acetate/hexane to 100% ethyl acetate/hexane to yield the title compound (10 mg, 34% yield).
