Procedure

A solution of 35.1 (200 mg, 0.43 mmol, 1.00 equiv), 5-fluoropyridin-2-amine (55 mg, 0.49 mmol, 1.13 equiv), HATU (200 mg) and DIPEA (170 mg) in distilled DMF (8 mL) was stirred at room temperature under nitrogen for 2 h. The reaction was then quenched with water and extracted with ethyl acetate (3×30 mL). The combined organic layers were washed with brine, dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was loaded onto a silica gel column with ethyl acetate/petroleum ether (1:2 to 3:5) to give tert-butyl N-(4-[[(3R)-3-[[(5-fluoropyridin-2-yl)carbamoyl]methyl]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]cyclohexyl)-N-methylcarbamate (36.1, 200 mg, 83%) as a yellow oil. MS: m/z 556 (M+H)+.
