Sodium triacetoxyborohydride (544 mg, 2.57 mmol) was added to (3R,7aR)-1-oxo-3-trichloromethyl-dihydro-pyrrolo[1,2-c]oxazole-7a-carbaldehyde (obtained as described in J. Org. Chem. 2006, 71(1), 97-102, 500 mg, 1.835 mmol), 3-fluorobenzylamine (0.251 mL, 2.20 mmol) and acetic acid (0.263 mL, 4.59 mmol) in DCE (4 mL) under an argon atm. The RM was stirred at rt for 3 h, then partitioned between water and DCM, the combined organic dried over Na2SO4 and evaporated to give the title compound as a pale yellow oil which was used without further purification.
