HCID 186915573-hydroxy-N-methoxy-N-methylcyclobutanecarboxamideYield 146.6%

Procedure

N-Methoxy-N-methyl-3-oxocyclobutanecarboxamide (1 g, 0.006 mol) was dissolved in methanol (8 mL, 0.2 mol). To the mixture, sodium borohydride (0.2 g, 0.006 mol) was added. The reaction was stirred at rt for 1 h. To the reaction mixture was added 1N aq. HCl to adjust the pH to 2. The mixture was concentrated, then extracted with EtOAc. The combined organic layers were dried over MgSO4 and concentrated to give crude product (1.4 g) as light yellow oil. LCMS calculated for C7H14NO3(M+H)+: 160.0; Found: 160.3.
