Reaction Steps

Diethyl (2RS,3RS)-2,3-epoxy-3(1-trityl-1,2,4-triazol-3-yl)propane phosphonate (0.39 g, prepared as described in Example 52) was treated with hydrochloric acid, as described in Example 53 for the (RS,SR) isomer, to give diethyl (2RS, 3RS)-3-chloro-2-hydroxy-3(1,2,4-triazol-3-yl)propane phosphonate (0.21 g) as a colourless oil, probably as its hydrochloride. NMR(D2O): δ 1.15(6H,t), 2.15(2H,m), 4.00(4H,m), 4.45(1H,m), 5.17(1H,d), 8.75(1H,s). (No internal standard, solvent signal at δ 4.67).
