Participants

Reaction Steps

To (3aR,5S,6S,7R,7aR)-2-(ethylamino)-6,7-dihydroxy-5,6,7,7a-tetrahydro-3aH-pyrano[3,2-d][1,3]thiazole-5-carbaldehyde (40.00 mg; 0.16 mmol; 1.00 eq.) in MeOH (1.00 ml) was added dimethylamine hydrochloride (15.89 mg; 0.19 mmol; 1.20 eq.), and sodium cyanoborohydride (5.10 mg; 0.08 mmol; 0.50 eq.) in 0.5 mL MeOH. The reaction was stirred at room temperature for 15 min. The desired product was isolated by flash chromatography (KPNH column, 0 to 100% MeOH/DCM, 15CV) to afford (3aR,5R,6S,7R,7aR)-5-[(dimethylamino)methyl]-2-(ethylamino)-5,6,7,7a-tetrahydro-3aH-pyrano[3,2-d][1,3]thiazole-6,7-diol (9.6 mg, 21%) as a white solid (once lyophilized).
