Participants

Reaction Conditions

Reaction Steps

Aldehyde 31.2 (162 mg, 0.574 mmol) was dissolved in MeOH (6 mL) and cooled to 0° C. Sodium borohydride (22.0 mg, 0.574 mmol) was added to the reaction. The solution was allowed to slowly warm to room temperature and was stirred for 1.5 hours. The reaction was quenched with dilute hydrochloric acid and then concentrated to dryness under reduced pressure. Water (20 mL) was added to the residue, and the mixture was extracted with EtOAc (2×50 mL). The organic layers were combined, washed with brine (1×30 mL), and dried over magnesium sulfate. The filtrate was concentrated to give 31.3 (151 mg). 1H NMR (400 MHz, CDCl3) δ ppm 7.38-7.43 (3H, m), 7.27-7.32 (3H, m), 7.20 (2H, d, J=8.2 Hz), 4.61 (2H, s).
