Reaction Steps

Utilizing a procedure analogous to that described in Example 1 (with conversion to the HCl salt as outlined for Example 2), this product was prepared in 74% yield from 6-bromo-5-fluoro-indoline (1.1 eq.), and 4-chloro-7-methoxy-quinazoline (1.0 eq) in i-PrOH. (M.P. 252°-252° C.; LC-MS: 374, 376 (MH+); anal. RP18-HPLC RT: 5.26 min.).
