Procedure

The title compound was prepared by the reaction of sodium salt of N-{4-[3-chloro-4-(trifluoromethoxy)phenyl]-1,3-thiazol-2-yl}-2-(1,3,6-trimethyl-2,4-dioxo-1,2,3,4-tetrahydrofuro[2,3-d]pyrimidin-5-yl)acetamide (2.0 g, 0.0036 mol) with chloromethyl pivalate (0.82 g, 0.005455 mol) in dry acetone (60 ml) to yield 390 mg of product as an off white solid. 1H NMR (300 MHz, CDCl3) δ 1.22 (s, 9H), 2.34 (s, 3H), 3.33 (s, 3H), 3.53 (s, 3H), 4.11 (s, 2H), 6.49 (s, 2H), 7.24 (s, 1H), 7.36 (d, J=7.8 Hz, 1H), 7.79 (d, J=8.7 Hz, 1H), 7.98 (s, 1H). ESI-MS (m/z): 642.75 (M+H)+.
