1. A method of producing a compound represented by the following formula (4) or a tautomer thereof, the process comprising
reacting a compound represented by the following formula (5) or a tautomer thereof with a compound represented by the following
formula (6) in the presence of an aluminum alkoxide compound:
 wherein R41 and R45 each independently represent a substituent selected from the group consisting of:
an alkyl group, an alkenyl group, an alkinyl group, an aralkyl group, an aryl group, a heterocyclic group, a halogen atom,
a hydroxyl group, an alkoxy group, an aryloxy group, a silyloxy group, a heterocyclic oxy group, an alkylthio group, an arylthio
group, a heterocyclic thio group, an alkylsulfinyl group, an arysulfinyl group, an alkylsulfonyl group, an arysulfonyl group,
a phosphino group, a phosphinyl group, a phosphinyloxy group, and a silyl group;
R42, R43 and R44 each independently represent a hydrogen atom, an aliphatic group, an aromatic group or a heterocyclic group; R51 represents an aliphatic group, an aromatic group or a heterocyclic group; n41 denotes an integer from 0 to 4; n45 denotes an integer from 0 to 5; when n41 is 2 or more, plural R41s may be the same or different and may be combined with each other to form a ring; and when n45 is 2 or more, plural R45s may be the same or different and may be combined with each other to form a ring.
