摘要:
Disclosed is a process for preparing a compound having the formula: wherein R, R1, R2, R3, and R4 are independently selected from the group consisting of H, Br, Cl, F, alkyl, or alkoxy, by (A) reacting a compound having the formula wherein RA, RC, RD, and RE are independently selected from the group consisting of H, halo, alkyl, or alkoxy, and R5 is aryl or heteroaryl, with a dehydrating agent to produce an imine having the formula: (B) hydrolyzing the imine produced in step (A) to produce the compound having formula (I). Also disclosed are novel intermediates having the formula: wherein RA, RB, RC, RD, and RE are independently selected from the group consisting of H, halo, alkyl, or alkoxy, and R5 is aryl or heteroaryl. Also disclosed is a process for preparing a compound having the formula: comprising: reacting a compound having the formula: with NH2R5 in the presence of a palladium catalyst, carbon monoxide, a base, and an ether selected from the group consisting of: CH3OCH2CH2OCH3; CH3OCH2CH2OCH2CH2OCH3; and CH3OCH2CH2OCH2CH2OCH2CH2OCH3, wherein X is H, Br, Cl, or F, and R5 is aryl or heteroaryl. The compounds made by these processes are useful intermediates for preparing compounds that are antihistamines or inhibitors of farnesyl protein transferase.
