反応手順

Sodium triacetoxyborohydride (4 g) was added to a solution of 3-trifluoromethyl-4-bromoaniline (1.5 g) and decanal (4 mL) in methanol (90 mL). After stirring for 1 h the solution was partitioned between water and petroleum ether. The organic extract was concentrated under reduced pressure and the residue was purified via flash column chromatography using petroleum ether as eluent to give N-Decyl-4-broma-3-trifluoromethylaniline (4) (1.2 g, 53%). 1H NMR (CDCl3) δ 7.44 (d, 1H, ArH); 6.92 (d, 1H, ArH); 6.61 (dd, 1H, ArH); 3.11 (t, 2H, NCH2); 0.80 (t, 3H, CH2CH3). TLC (silica gel): Rf=0.35 (petroleum ether).
