A mixture of 6-chloro-3-(4-(2-hydroxy-2-methylpropoxy)-3-methoxyphenyl)-pyrimidin-4(3H)-one Part A of Procedure 11 (11 mg, 0.03 mmol), 4-ethylphenylboronic acid (7.6 mg, 0.05 mmol), potassium phosphate tribasic (21.57 mg, 0.102 mmol), and PalladiumTetrakis (4 mg, 3.39 μmol) in DMF (0.5 mL) was stirred at 90° C. overnight. The reaction was diluted with CH2Cl2, filtered, and concentrated. The crude was purified using HPLC (Phen Luna Axia C18 5μ 10:90:0.1 to 90:10:0.1 MeOH—H2O-TFA) to afford the desired product 6-(4-ethylphenyl)-3-(4-(2-hydroxy-2-methylpropoxy)-3-methoxyphenyl)pyrimidin-4(3H)-one M-1 (9.93 mg, 0.02 mmol, 69.1% yield) as a light yellow solid. LC/MS 395 (M+H)+, tR 0.95 min (method 5). 1H NMR (500 MHz, CHLOROFORM-d) d ppm 8.25 (1H, s), 7.93 (2H, d, J=8.32 Hz), 7.34 (2H, d, J=8.32 Hz), 7.02 (1H, d), 6.91-6.96 (3H, m), 3.90 (3H, s), 3.89 (2H, s), 2.74 (2H, q), 1.38 (6H, s), 1.30 (3H, t, J=7.63 Hz)
