Procedure

A mixture of 4-(4-bromo-2-cyclopropyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-5-yl)-2-chloropyrimidine (5.50 g, 12.8 mmol), (S)-tert-butyl 1-aminopropan-2-ylcarbamate (SM-1, 2.68 g, 15.4 mmol), diisopropylethylamine (2.68 mL, 15.4 mmol) and sodium carbonate (2.71 g, 25.6 mmol) in NMP (8 mL) was heated with 110° C. oil bath for 3.5 hours and LCMS analysis of an aliquot indicated reaction completion with desired product. The reaction was allowed to cool to ambient temperature, then partitioned between EtOAc (20 mL) and water (60 mL). The EtOAc layer was washed with water (60 mL), dried (Na2SO4), and concentrated to a light yellow foam (6.89 g, 12.1 mmol). A small portion of material was further purified by flash chromatography (SiO2, EtOAc in heptane): LCMS (m/z) 567.3 (MH+), tR=1.03 minutes; 1H NMR (CDCl3, 300 MHz) δ −0.09 (s, 9H), 0.80 (t, J=8.2 Hz, 2H), 0.98-1.07 (m, 2H), 1.10-1.18 (m, 2H), 1.21 (t, J=6.5 Hz, 3H), 1.40 (s, 9H), 1.91-2.08 (m, 1H), 3.41 (t, J=8.2 Hz, 2H), 3.44-3.59 (m, 2H), 3.82-4.01 (m, 1H), 4.65-4.87 (m, 1H), 5.41-5.61 (m, 1H), 5.78-5.99 (m, 2H), 7.10 (d, J=5.0 Hz, 1H), 8.33 (d, J=5.2 Hz, 1H).
