Procedure
A solution of 8-((3-fluorophenyl)ethynyl)-2,3,4,5-tetrahydro-[1,4]diazepino[7,1-b]quinazolin-11(1H)-one (0.1 g, 0.3 mmol), methyl formate (22 mg, 1.2 mmol), and 2,3,4,6,7,8-hexahydro-1H-pyrimido[1,2-a]pyrimidine (2.1 mg, 0.015 mmol) in toluene (3 mL) was stirred at room temperature for 12 h. The reaction mixture was quenched with saturated potassium bisulfate (5 mL). The solution was extracted with ethyl acetate (3×20 mL) and the combined organic layers were washed with brine, dried over Na2SO4. After filtration and concentration, the residue was purified by silica gel chromatography to give the desired product. MS (ESI): 362 (M+H+); 1H NMR (300 MHz, CDCl3) δ 8.27-8.23 (m, 1H), 8.20-8.18 (d, J=6.24 Hz, 1H), 7.79-7.78 (m, 1H), 7.62-7.59 (m, 1H), 7.38-7.32 (m, 2H), 7.29-7.26 (m, 1H), 7.14-7.07 (m, 1H), 4.57-4.49 (m, 2H), 3.94-3.84 (m, 2H), 3.75-3.65 (m, 2H), 3.28-3.19 (m, 2H). mGluR5 PAM EC50: +++. Fold shift at 10 μM: ++.
