N-(tert-butoxycarbonyl)glycine → HCID 57947854, compound

Participants

Reaction Steps

To a solution of (S)-5-amino-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)pentyl 6-fluoroisoquinolin-3-ylcarbamate (96 mg, 0.19 mmol), 2-(tert-butoxycarbonylamino)acetic acid (51 mg, 0.29 mmol) and HBTU (110 mg, 0.29 mmol) in DMF (1.0 mL) was added DIEA (63 L, 0.38 mmol). The mixture was stirred at RT for 30 min. The mixture was filtered and the filtrate was purified by RP-HPLC using a mixture of acetonitrile and water to give (6-Fluoro-isoquinolin-3-yl)-carbamic acid (S)-5-(2-tert-butoxycarbonylamino-acetylamino)-2-[3-(2-chloro-3-fluoro-benzyl)-1-methyl-ureido]-pentyl ester (105 mg, 83%). LRMS (M+Na+) m/z 663.2.
