Methyl 6-cyano-7-fluoro-2,2-dimethylchroman-4-carboxylate (19 mg, 0.072 mmol) was diluted with N-methylpyrrolidone (2 mL) followed by the addition of K2CO3 (25 mg, 0.18 mmol) and N-(4-chlorophenethyl)-4-hydroxybenzamide (20 mg, 0.072 mmol). The reaction was bubbled with argon for 10 minutes and then heated at 110° C. for 6 hours. After cooling, the reaction mixture was loaded directly onto a Biotage 25 column and eluted with 5% ethyl acetate/hexanes to 100% ethyl acetate to yield the title compound (2.0 mg, 5.3% yield).
