合成路线1
该中间体在本合成路线中的序号：(XI)The condensation of acetone (VIII) with 2-methoxybenzaldehyde (IX) by means of NaOH gives 2-methoxybenzalacetone (X), which is reduced with H2 over Raney-Ni in ethanol to yield 4-(2-methoxyphenyl)-2-butanone (XI). The Grignard reaction of (XI) with methylmagnesium iodide in ether affords 1,1-dimethyl-3-(2-methoxyphenyl) propanol (XII), which by reaction with NaCN by means of H2SO4 in acetic acid affords N-[1,1-dimethyl-3-(2-methoxyphenyl)propyl]formamide (XIII). Finally, this compound is hydrolyzed with refluxing 5N NaOH to give (II).
