To a solution of (1aR,5aR)-1a,2,5,5a-tetrahydro-1H-2,3-diazacyclopropa[a]pentalene-4-carboxylic acid (40 mg, 0.24 mmol), HATU (93 mg, 0.24 mmol) in DMF (1 mL) was added Et3N (25 mg, 0.24 mmol). After stirring for 5 min at room temperature, 2-phenylpropan-2-amine (33 mg, 0.24 mmol) was added to the reaction. After stirring for an additional 1 h, 4-(2-chloroethyl)morpholine hydrochloride (45 mg, 0.24 mmol) and Cs2CO3 (79 mg, 0.24 mmol) was added into the reaction. The reaction was microwaved for 3.5 h at 150° C., filtered, and purified by preparative HPLC to give the title compound (12 mg). LCMS m/z=395.5 [M+H]+; 1H NMR (400 MHz, CDCl3) δ ppm 0.38 (td, J=4.6 and 3.5 Hz, 1H), 1.10 (td, J=7.8 and 4.7 Hz, 1H), 1.78 (s, 6H), 2.00-2.06 (m, 1H), 2.16-2.23 (m, 1H), 2.48-2.52 (m, 4H), 2.76-2.94 (m, 4H), 3.67-3.72 (m, 4H), 4.17 (t, J=6.8 Hz, 2H), 7.07 (bs, 1H), 7.21 (t, J=8.0 Hz, 1H), 7.32 (t, J=8.0 Hz, 2H), 7.42-7.47 (m, 2H).
