Reaction Steps

Utilizing a procedure analogous to that described in Example 1, this product was prepared in 88% yield from 6-methyl-indoline (1.1 eq.) and 4-chloro-6,7-dimethoxy-quinazoline (1.0 eq) in i-PrOH. The HCl salt was generated from the purified free base according to the procedure given in Example 2 (M.P. 231°-232° C.; LC-MS: 322 (MH+); anal. RP18-HPLC RT: 4.32 min.).
