Reaction Steps

1-{6-[4-(1,1-Dimethyl-propyl)-cyclohexyloxy]-quinazolin-2-ylmethyl}-pyrrolidine-3-carboxylic acid methyl ester (229.50 mg, 5.2208E-4 mol) was dissolved in Methanol (5 mL, 0.1 mol) and Tetrahydrofuran (5 mL, 0.06 mol), followed by 2 M of Lithium hydroxide in Water (2 mL, 0.004 mol) at at 23° C. for 10 minutes. Excess of solvents were removed under vacuum, and the solid residue was treated with HCl (2N, 3 mL), and extracted with DCM (20×3 mL). The organic layers were dried over Na2SO4. Removal of solvent gave a pure product (200 mg, 90%). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 0.69-0.94 (m, 12H) 1.13-1.37 (m, 10H) 1.39-1.59 (m, 2H) 1.76-1.96 (m, 3H) 2.18-2.37 (m, 2H) 4.84 (br. s., 1H) 7.16-7.38 (m, 2H) 7.55-7.71 (m, 1H) 7.99 (br. s., 1H) MS (ESI, M+1): 426.30.
