Participants

Reaction Steps

2-Amino-5-chlorobenzoic acid (0.25 g) and 3,3-difluoro-azetidine hydrochloride (0.24 g) were reacted according to the method of Example 332C. The resultant intermediate (0.16 g) was then reacted with 2-oxaadamantane 1-carbonylchloride (1.25 equiv) (prepared from 2-oxaadamantane 1-carboxylic acid and thionyl chloride as in Example 12) and triethylamine (2 equiv) in acetonitrile (10 mL). Evaporation of solvents and flash chromotography over silica gel (20% ethyl acetate/hexane) provided 190 mg of the title compound. 1H NMR (dimethylsulfoxide-d6, 300 MHz) δ 1.66-2.03 (m, 10H), 2.19 (br s, 2H), 4.36-4.81 (br, 4H), 7.54 (dd, 1H), 7.59 (d, 1H), 8.18 (d, 1H), 10.52 (s, 1H); MS (ESI+) m/z 411 (M+H)+.
