Reaction Steps

A solution of tert-butyl 3-[3-(1-{[(benzyloxy)carbonyl]amino}ethyl)-5,6-dichloro-2-methoxyphenyl]azetidine-1-carboxylate [peak 2 isomer from step 6] (0.29 g, 0.57 mmol) in methanol (17 mL) and 0.25 M HCl in water (5.7 mL, 1.4 mmol) was degassed with nitrogen, treated with 5% Pt/C (Degussa type) (73 mg, 25 wt %), and stirred under a balloon of hydrogen for 1 hour. The reaction mixture was treated with additional 5% Pt/C (Degussa type) (100 mg) and stirred under a balloon of hydrogen for an additional 1 hour. The reaction mixture was filtered over Celite and neutralized with saturated sodium bicarbonate solution. The reaction mixture was concentrated to remove the methanol, extracted with dichloromethane, and concentrated to give the desired product (0.21 g, 99%) as a colorless foam that was used without further purification. LCMS for C13H14C12NO3 (M−[NH2]−[t-Bu]+H)+: m/z=302.0, 304.0. Found: 301.9, 304.0.
