Participants

Reaction Steps

Crude 18-2 (115 mg, 0.24 mmol) was suspended in anhydrous CH2CL2 (3 mL) and treated successively with 4-amino-1-tert-butyloxycarbonyl-piperidine (235 mg, 1.17 mmol) and Et3N (0.1 mL, 0.7 mmol). The suspension was stirred for 6 hours and complete dissolution was observed. Upon completion, the reaction was diluted further with CH2Cl2 (20 mL) and washed with 1N HCl to remove all unbound amine and Et3N. The organic layer was dried (MgSO4), filtered and concentrated under reduced pressure to yield crude 18-3 as a yellow oil: LRMS m/z (N C(CH3)3+H) 427.9 found, 428.1 required.
