実験手順

A solution of 2,3,4-trifluorobenzaldehyde (25 g, 156.16 mmol), 2,2-dimethoxypropane (58.1 ml, 468.48 mmol), and 4-methylbenzenesulfonic acid (0.269 g, 1.56 mmol) was stirred at room temperature overnight. The reaction mixture diluted with ether and washed successively with aq. sodium bicarbonate solution, water, and brine. The organic layer dried over sodium sulfate and concentrated. The residue wasdistilled under high vacuum to give the title compound (23.07 g, 71.7%).
