Reaction Steps

A solution of [(2S,4R,5R)-5-(5-amino-2,7-dioxo-6H-thiazolo[4,5-d]pyrimidin-3-yl)-4-(2-methylallyl)tetrahydrofuran-2-yl]methyl benzoate (compound 41b, 180 mg, 0.41 mmol) in methanol was stirred with K2CO3 (150 mg, 1.09 mmol) at room temperature for 4 hours. The reaction was quenched by addition of acetic acid and the resulting mixture was concentrated in vacuo. The residue was purified by preparative HPLC to afford 41 mg of 3-[(2R,3R,5S)-3-allyl-5-(hydroxymethyl)tetrahydrofuran-2-yl]-5-amino-6H-thiazolo[4,5-d]pyrimidine-2,7-dione (Example 41) as a white powder.
