Participants

Reaction Steps

4-Piperidinemethanol (17.7 g, 1.0 eq.), 3,5-difluorocinnamic acid (28.3 g, 1.0 eq.) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (BOP, 78.2 g, 1.15 eq.) were dissolved in dichloromethane (DCM, 700 mL). Triethylamine (TEA, 46.6 g, 3.0 eq.) was added and the resulting solution was stirred at room temperature overnight. LCMS showed 100% conversion. The reaction mixture was concentrated and purified via silica gel column eluting with 0-75% ethyl acetate in hexanes to afford the product as a white solid (35 g, 81%). MS (ES) m/e 282 [M+H]+.
