Procedure

To the mixture of 1-(4-(diethoxymethyl)phenyl)-N,N-dimethylmethanamine (7.0 g, 29.5 mmol) in hydrogen chloride (3M in water 30 mL) was stirred at room temperature for 5 hr. Then the mixture was extracted with ethyl acetate (50 ml×3). The aqueous layer was basified with sodium carbonate to pH=10, extracted with ethyl acetate (50 ml×3), dried with anhydrous sodium sulfate, and concentrated to give crude product (3.95 g, yield 82%). LC-MS (ESI) m/z: 164 (M+1)+.
