Procedure

1-[6-(4-tert-Butyl-cyclohexyloxy)-quinolin-2-yl]-ethanone (68 mg, 0.00021 mol) and Azetidine-3-carboxylic acid methyl ester (23.9 mg, 0.000207 mol) was dissolved in Ethanol (0.50 mL, 0.0086 mol) and was heated to reflux for 2 hours. After cooling down to rt, Sodium cyanoborohydride (32.4 mg, 0.000516 mol) was added and was heated to reflux for 1 hour. After cooling down to rt and concentration, the mixture was dissolved into DCM and quenched with NEt3 and concentrated. The residue was chromatographed with MeOH/CH2Cl2 to give product (57.2 mg, 65%). LCMS 1.66 min, at m/z 425.30 ([M+1], 100%).
