Reaction Conditions

Reaction Steps

The reaction was carried out under argon. 4-(1,3-Dioxan-2-yl)-3-fluorobenzonitrile (207 mg, 1 mmol) and thiophenol (100 mg, 0.9 mmol; 1.1 eq.) were initially charged in DMF (3 ml). Potassium carbonate (314 mg, 2.27 mmol; 2.5 eq.) was added at RT, and the mixture was stirred at 100° C. for 4 h. LC/MS control then showed complete conversion. The reaction mixture was purified directly by preparative HPLC (column: Gromsil C-18; mobile phase: acetonitrile/water+0.1% TFA 10:90→90:10). The title compound was obtained as a solid (238 mg, 80% of theory).
