Reaction Steps

To a solution of the thus obtained (2S,4R)-1-p-methoxybenzyloxycarbonyl-4-hydroxy-2-azidomethylpyrrolidine (5.57 g: 18.18 mmole) in methanol (30 ml) are added, 5% palladium on charcoal (560 mg) and ammonium formate (2.3 g). The mixture is stirred at 45° C. for 2 hours. The reaction mixture is diluted with dichloromethane (50 ml), filtered to remove the catalyst, and concentrated in vacuo. The residue is crystallized from a mixture of dichloromethane and ether and washed with ether to give (2S,4R)-1-p-methoxybenzyloxycarbonyl-4-hydroxy-2-aminomethylpyrrolidine formate (4.28 g). Yield: 72%. NMR δ(CDCl3 --CD3OD) ppm: 1.6 to 1.82(m, 1H), 2.1 to 2.3(m, 1H), 2.7 to 3.7(m, 4H), 3.81(s, 3H), 4.1 to 4.4(m, 2H), 5.04(s, 2H), 6.88(d, J=8.8 Hz, 2H), 7.28(d, J=8.8 Hz, 2H), 8.47(s, 1H). IR ν (CHCl3) cm-1 : 3678, 3412, 1678, 1602.
