How is 4-Methoxylonchocarpin (CAS: 51589-67-4) typically synthesized?

4-Methoxylonchocarpin (CAS: 51589-67-4) is typically synthesized through a multi-step process involving the reduction of a precursor compound, followed by methylation. The synthesis requires the use of a suitable reducing agent (such as sodium borohydride) and a methylation reagent (like dimethyl sulfate). The reaction is carried out under anhydrous conditions and requires careful control of temperature and pH to achieve high yield and selectivity.
