Participants

Reaction Steps

Sodium hydroxide (1 mL, 2M, 2 mmol) was added to a solution of methyl {(7R)-2-amino-8-[(4-methoxy-3,5-dimethylpyridin-2-yl)methyl]-6-oxo-5,6,7,8-tetrahydropteridin-7-yl}acetate (272 mg, 0.26 mmol)(Example 7[3]) in methanol (1 mL) and THF (3 mL). The mixture was stirred for 2 hours and then concentrated under reduced pressure. The solution was diluted with water (1 mL) and made acidic by the addition of acetic acid. This solution was loaded onto an SCX column, washed with water and then methanol and the product was eluted with 2M ammonia in methanol. Thus, the title compound was obtained as a cream solid (169 mg, 65%); 1H NMR spectrum (400 MHz, DMSO-d6) δ 2.18 (6H, s), 2.29 (1H, d), 2.38 (1H, d), 3.72 (3H, s), 4.13-4.15 (1H, m), 4.41 (1H, d), 5.49 (1H, d), 5.55 (2H, s), 7.27 (1H, s), 8.13 (1H, s), 9.91 (1H, s); Mass spectrum: (M+H)+ 373.
