HCID 598514512-[4-(3-Amino-prop-1-ynyl)-phenylamino]-9-chloro-5H,7H-benzo[b]pyrimido[4,5-d]azepin-6-one

Procedure

In a manner similar to that described for Method O, 9-chloro-2-(4-iodo-phenylamino)-5H,7H-benzo[b]pyrimido[4,5-d]azepin-6-one (I-36) and tert-butyl prop-2-ynylcarbamate were converted to {3-[4-(9-chloro-6-oxo-6,7-dihydro-5H-benzo[b]pyrimido[4,5-d]azepin-2-ylamino)-phenyl]-prop-2-ynyl}-carbamic acid tert-butyl ester, which was deprotected according to Method K to give I-46 (29%): HRMS Calcd. for C21H16ClN5O: 390.1121, Found 390.1120.
