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.
