Abstract:
Disclosed herein is a novel process for preparing substituted quinazoline compounds of formula (I) using a hydrogen bonding catalyst.

Claim (Index 9):
A process for preparing a compound of Formula (I): or a salt thereof, comprising contacting a compound of formula (viii): or a salt thereof, with a catalyst of formula (VI): wherein each occurrence of R 7  is independently selected from the group consisting of phenyl, naphthyl, phenanthrenyl, pyridyl and thiophenyl, each of which is optionally substituted with one to five substituents independently selected from halogen and \u2014CF 3 ; and each occurrence of R 8  is hydrogen; in a suitable solvent for a time sufficient to form a compound of formula (I); wherein: R 1  represents up to 3 phenyl group substituents, each independently selected from C 1 -C 6  alkyl, C 1 -C 6  haloalkyl, halo, \u2014CN, \u2014OH and C 1 -C 6  alkoxy; R 2  represents up to 3 phenyl group substituents, each independently selected from C 1 -C 6  alkyl, C 1 -C 6  haloalkyl, halo, \u2014CN, \u2014OH and C 1 -C 6  alkoxy; R 3  represents up to 3 phenyl group substituents, each independently selected from C 1 -C 6  alkyl, C 1 -C 6  haloalkyl, halo, \u2014CN, \u2014OH and C 1 -C 6  alkoxy; and R 4  is C 1 -C 6  alkyl or C 3 -C 7  cycloalkyl.
