A solution of ethyl 6-(allyloxy)-5-(benzyloxy)-2-(4-(hydroxymethyl)piperidin-1-yl)pyrimidine-4-carboxylate (1.206 g, 2.82 mmol) in n-propanol (10 mL) was sparged with N2. Rhodium(III) chloride (0.030 g, 0.141 mmol) was added and the resulting mixture was stirred overnight at 100° C. The mixture was cooled to room temperature and partitioned between water and CH2Cl2. The organic phase was dried (Na2SO4), filtered and concentrated to give a yellow solid that was triturated with Et2O. The product was collected by filtration to give the title compound as a white solid (0.8252 g, 76% yield). 1H NMR (300 MHz, CDCl3) δ: 7.43 (2H, d, J=7.3 Hz), 7.37-7.29 (3H, m), 5.05 (2H, s), 4.46 (2H, d, J=13.1 Hz), 4.31 (2H, q, J=7.1 Hz), 3.44 (2H, d, J=5.8 Hz), 2.94-2.88 (2H, m), 1.74 (2H, d, J=13.1 Hz), 1.73-1.66 (1H, m), 1.29 (3H, t, J=7.2 Hz), 1.28-1.22 (2H, m). LCMS (M+H) calcd for C20H26N3O5: 388.18; found: 388.23.
