Procedure
A solution of (3aR,5R,6S,7R,7aR)-5-(acetoxymethyl)-2-(methylamino)-5,6,7,7a-tetrahydro-3aH-pyrano[3,2-d]thiazole-6,7-diyl diacetate (150 g, 417 mmol) in methanol (1 L) was treated with potassium carbonate (11.5 g, 83 mmol). The resulting mixture was stirred overnight at room temperature to yield a solid. This was collected by filtration, washed with cold methanol and dried. The product 24 was obtained as a yellow solid (85 g, 87%). (ES, m/z): [M+H]+ 235.1; 1H NMR (300 MHz, D2O) δ 6.14-6.16 (d, J=6.3 Hz, 1H), 4.03-4.07 (m, 1H), 3.89-3.92 (m, 1H), 3.65-3.70 (m, 1H), 3.48-3.56 (m, 2H), 3.41-3.45 (m, 1H), 2.69 (s, 3H).
