How is Methyl 3-(hydroxymethyl)cyclobutanecarboxylate (CAS: 89941-55-9) typically synthesized?

Methyl 3-(hydroxymethyl)cyclobutanecarboxylate (CAS: 89941-55-9) is typically synthesized through the addition of methanol to 3-chlorocyclobutanone in the presence of a base such as potassium hydroxide. The reaction is conducted in a polar aprotic solvent like dimethylformamide (DMF) at room temperature, yielding a mixture of diastereomers with high selectivity. The product is then isolated and purified by recrystallization.
