A solution of N′-({[(3aS,4S,6R,6aR)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl]carbonyl}oxy)propanimidamide (Preparation 12) (5.85 g, 20 mmol) in 2-methoxyethyl ether (20 ml) was heated at 120° C. for four hours. The reaction mixture was allowed to cool to room temperature and evaporated under reduced pressure. The final traces of 2-methoxyethyl ether were removed by co-evaporation with first xylene and then toluene. The title compound was obtained as a dark orange oil (5.22 g).
