Yield: 85%

Reaction Conditions:

with triethylamine;tin(ll) chloride at 5 - 19; for 32.3333 h;Concentration;Temperature;

Steps:

3 Example 3
In the is provided with an agitator, reflux condenser, thermometer, dropping funnel in the reaction container, adding triethylamine to 310 ml, stannous chloride 0.65mol, control the stirring speed 190rpm, reducing the temperature of the solution to 5 °C, β-naphthyl methyl ether is slowly added (2) 0.65mol, adds by drops third amide (3) 0.47mol, dropping time control, in 80 min, maintaining the temperature of the solution reaction 9h, raising the temperature of the solution to 19 °C, standing 22h, the reactants are poured into the 1.8L the mass fraction of 25% sodium bisulfite solution, control the temperature of the solution in the 5 °C, steam distillation, until completely distilled until the triethylamine, control the stirring speed 130rpm, let solution of natural cooling, solidifying oily substance, filtering, potassium nitrate solution, anhydrous calcium sulfate dehydration, in the mass fraction is 92% recrystallized in cyclohexane solution, to get the yellow solid 6-methoxy-2-c acyl-naphthaline 85.49g, yield 85%.
