Procedure

Following the general procedure for the one pot synthesis, ACPC (1.02 g, 9.8 mmol) was reacted with chlorotrimethylsilane (2.48 mL, 19.7 mmol) in anhydrous chloroform in the presence of DIEA (3.64 mL, 19.7 mmol). Subsequent reaction of the intermediate with 1-chloro-2-methylpropyl chloroformate (1.6 mL, 14.8 mmol) followed by a mixture of DIEA (3.64 mL, 19.7 mmol) and admantane carboxylic acid (3.5 g, 19.7 mmol) provided 0.220 g (6.4% yield) of the title compound (22) as a white solid after aqueous work-up and mass-guided preparative HPLC purification. 1H NMR (CDCl3, 400 MHz): δ=6.81 (q, 1H), 5.62 (s, 0.2H), 5.38 (s, 0.8H), 2.09 (m, 4H), 1.93 (m, 6H), 1.72 (m, 6H), 1.61 (s, 2H), 1.52 (d, 3H), 1.37 (br s, 2H). MS (ESI) m/z 374.01 (M+H)+, M−H=350.04 (M−H)−.
