实验步骤: 2-Hydroxy-1-naphthaldehyde (10 g., 0.058 mole) was combined with acetone (120 ml.), iodoethane (9.9 g., 0.063 mole) and anhydrous potassium carbonate (8.0 g., 0.058 mole) and the mixture heated to reflux for 48 hours. The reaction mixture was cooled to room temperature, filtered and filtrate evaporated to solids (9.0 g.) Recrystallization from isopropyl ether afforded purified 2-ethoxy-1-naphthaldehyde in two crops (4.5 g. and 0.5 g., m.p. 106°-109° C.). the mixture heated to reflux for 48 hours filtered filtrate evaporated to solids (9.0 g.) Recrystallization from isopropyl ether afforded purified 2-ethoxy-1-naphthaldehyde in two crops (4.5 g. and 0.5 g., m.p. 106°-109° C.)

实验步骤: To a solution of benzothiazol-2-yl-piperidin-4-yl-amine (23.3 mg, 0.1 mmol, 1.0 equiv) and 2-ethoxy-naphthalene-1-carbaldehyde (commercially available, 24.0 mg, 0.12 mmol, 1.2 equiv) in ethanol (2 mL) was added diisopropylethylamine (23.42 μL, 25.9 mg, 0.2 mmol, 2.0 equiv) and acetic acid (18.0 mg, 0.3 mmol, 3.0 equiv) and the mixture stirred at 40° C. After 1 h, sodium cyano borohydride (7.54 mg, 0.12 mmol, 1.2 equiv) was added and the mixture stirred at 40° C. over night. Removal of the solvent under reduced pressure and purification by preparative HPLC on reversed phase eluting with a gradient of acetonitrile/water provided 3.3 mg (8%) of the title compound. MS (ESI): 418.4 [M+H]+. the mixture stirred at 40° C. over night Removal of the solvent under reduced pressure and purification by preparative HPLC on reversed phase eluting with a gradient of acetonitrile/water
