Reaction Steps

A solution of ethyl 2-(8-(benzyloxycarbonylamino)-1,4-dioxaspiro[4.5]decan-8-yl)-5-hydroxy-6-oxo-1,6-dihydropyrimidine-4-carboxylate (1.8 g, 3.8 mmol) in THF (200 mL) was added 2N HCl (12 ml, 24 mmol) and the resulting mixture was heated for 2 h at 60° C. The reaction mixture was then cooled and extracted with CH2Cl2 (3×100 mL). The CH2Cl2 fractions were dried (Na2SO4), filtered and concentrated to afford the title compound as a light yellow solid (1.5 g, 92% yield). 1H NMR (500 MHz, CDCl3) δ: 12.11 (s, 1H), 11.09 (s, 1H), 7.17-7.29 (m, 5H), 6.36 (s, 1H), 5.00 (s, 2H), 4.44 (q, 2H, J=7.02 Hz), 2.49-2.57 (m, 8H), 1.42 (q, 3H, J=7.05 Hz). LCMS (M+H)=430.38.
