実験手順

Methyl 6-cyano-7-fluoro-4-methylchroman-4-carboxylate (10 mg, 0.040 mmol) was diluted with N-methylpyrrolidone (2 mL) followed by the addition of K2CO3 (28 mg, 0.20 mmol) and N-(4-chlorophenethyl)-4-hydroxybenzamide (11 mg, 0.040 mmol). The reaction was bubbled with argon for 10 minutes and then heated at 110° C. and stirred for 5 hours. The reaction was allowed to cool, loaded directly onto a 25 samplet and eluted on the horizon with 5% ethyl acetate/hexanes to 100% ethyl acetate/hexanes to yield the title compound (12 mg, 59% yield). MS (ESI)=504.9 (M+1).
