Procedure

A reaction vessel was charged with N-benzoyl-L-threonine (56 mg), HOBt (42 mg), DIEA (130 μL), 4-(4-chlorophenyl)-4-hydroxypiperidine (66 mg), EDC (60 mg), DMF (1 mL) and 1,2-dichloroethane (1 mL). The reaction mixture was stirred for 16 h at rt and then diluted with methanol (0.5 mL). Upon completion of dilution, the reaction mixture was purified by preparative LC-MS to provide Example 226. MS found: (M+H)+=399.
