Reaction Conditions

Reaction Steps

To a flask containing ethyl 3-(4-(3,3-dimethylcyclobutanecarbonyl)benzamido)propanoate (1.21 g, approximately 2.55 mmol pure) was added anhydrous methanol (18.3 mL). The solution was cooled to 0° C. and sodium borohydride (414 mg, 11.0 mmol) was added. After 15 min., the reaction was quenched with saturated aqueous ammonium chloride and extracted three times with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered, and concentrated to give 1.10 g of crude material. Purification by silica gel flash chromatography (0-50% ethyl acetate in heptane) afforded impure ethyl 3-(4-((3,3-dimethylcyclobutyl)(hydroxy)methyl)benzamido)propanoate (750 mg, approximately 1.8 mmol pure) as an oil. MS (M+1): 334.3.
