]quinazolines Using Trialkylamines as Alkyl Synthon
the construction of 2-alkyl substituted quinazolin-4(3H)-ones and benzo[4,5]imidazo[1,2-c]quinazolines using trialkylamines as carbon synthons has been developed. Some of the notable features of this methodology include the synthesis of potent central nervous system depressants (CNS) drug molecules methaqualone (3 la), mecloqualone (3 pa) and gram-scale synthesis.

The invention relates to methods for treating pruritus with NK-1 receptor antagonists such as serlopitant. The invention further relates to pharmaceutical compositions comprising NK-1 receptor antagonists such as serlopitant. In addition, the invention encompasses treatment of a pruritus-associated condition with serlopitant and an additional antipruritic agent, and the use of serlopitant as a sleep aid, optionally in combination with an additional sleep-aiding agent.
