Claim 15:
16. The process according to claim 14, characterized in that, the step a) is carried out by: (i) simultaneously entering the compound of formula (II) and the alcohol of formula (III) and the compound of formula (V) into a first microchannel reactor to react with each other in the presence of a solvent, and then entering the resultant product and a base, into a second microchannel reactor together; or (ii) simultaneously entering the compound of formula (II) and the alcohol of formula (III) into a first microchannel reactor to react with each other in the presence of a solvent or in the absence of a solvent, then entering the resultant product and the compound of formula (V) into a second microchannel reactor, and finally entering the resultant product and a base, into a third microchannel reactor together to react with each other; or (iii) simultaneously entering the compound of formula (II) and the compound of formula (V) into a first microchannel reactor to react with each other in the presence of a solvent or in the absence of a solvent, then entering the resultant product and the alcohol of formula (III) into a second microchannel reactor, and finally entering the resultant product and a base, into a third microchannel reactor together to react with each other; or (iv) simultaneously entering the compound of formula (II) and the alcohol of formula (III) into a first microchannel reactor to react with each other in the presence of a solvent or in the absence of a solvent, and then entering the resultant product, the compound of formula (V) and a base, into a tube reactor together to react with each other.
