With toluene-4-sulfonic acid; at 90℃; for 12h;Inert atmosphere; Sealed tube; | To 1.00 g (1.00 mL, 9.33 mmol) of o-toluidine in a pressure tube was added 1.41 mL (1.1 eq. 10.3 mmol) of hexafluoroacetone sesquihydrate neat and 0.180 g (0.1 eq, 0.933 mmol) p-toluenylsuphonic acid. The tube was then purged with argon, sealed and heated on an oil bath overnight (12 h) at 90 C. The reaction contents were then diluted with 200 mL ethyl acetate and washed 3*150 mL NaHCO3 (sat.). The ethyl acetate phase was then washed with 50 mL brine, dried with Na2SO4, and concentrated to a solid residue. The desired product was then isolated by silica gel using hexanes/ethyl acetate and following recrystallization from 10:1 hexanes/ethyl acetate to afford of 2-(4-amino-3-methyl-phenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol as white prisms. ESI-MS (m/z): 274 [M+1]+. |
