Procedure

146 mg (0.34 mmol) of (R)-2-amino-1-(3-butoxy-3-o-tolylazetidin-1-yl)-3-(4-methoxyphenyl)propan-1-one hydrochloride in 2 ml of dimethylformamide are added to a solution of 47 mg (0.34 mmol) of 3-(1H[1,2,3]triazol-4-yl)propanoic acid, 119 mg (0.37 mmol) of TBTU and 0.15 ml (1.1 mmol) of triethylamine in 2 ml of dimethylformamide. The reaction mixture is stirred for 2 hours at ambient temperature. The reaction is stopped by adding 10 ml of water and then extracted with ethyl acetate. The organic phases are combined, washed with a 1N solution of sodium hydroxide and then a saturated solution of sodium chloride, and dried over sodium sulphate. After filtration, the solvents are evaporated off and the residue is then purified by silica gel chromatography (eluent 90/10 ethyl acetate/heptane). 78.6 mg of N—[(R)-2-(3-butoxy-3-o-tolylazetidin-1-yl)-1-(4-methoxybenzyl)-2-oxoethyl]-3-(1H[1,2,3]triazol-4-yl)propionamide are obtained in the form of a white powder with a yield of 45%.
